These sensors use ZMTrigger.pl (wiki.zoneminder.com/ZMTrigger) to activate an alarm on a camera for a period of time. The advantage of hardware motion sensors over the software detection of Zoneminder, is that the hardware motion sensors avoid some of the problems inherent in software detection, such as false positives from day-to-night, bugs, missed detections, and others. +\section{Work Log} + + + + +%\includegraphics[scale=0.8]{../pics/resistances.png} +%\captionof{figure}{Application Note resistance table} + + + + + + + + +\end{document} + diff --git a/ZMHW_Modector/docs/1.tex~ b/ZMHW_Modector/docs/1.tex~ new file mode 100644 index 0000000..2233473 --- /dev/null +++ b/ZMHW_Modector/docs/1.tex~ @@ -0,0 +1,63 @@ + +\documentclass[11pt]{article} +%Gummi|065|=) +\usepackage{graphicx} +\usepackage{caption} +\title{\textbf{Flammable Gas Sensor}} +\author{Steak Electronics} +\date{} +\begin{document} + +\maketitle + +\tableofcontents + +\section{Overview} +Shop needs a flammable gas sensor, for safety. +\section{Chip Hunting} +I'm looking at the following: + +\begin{itemize} +\item SGAS711 +\item 200K fixed resistor +\item 1M potentiometer +\item Arduino Nano (for speed) +\item Ample Power Supply They are recommending 7 Volts for the heater. So, one rated for 1A. +\item led notifiers + \item + +\end{itemize} + + +\subsection{Gas Sensor Tuning} +The flammable gas sensor has different sensitivities for different gases (see data sheet, Figure 8). I'm going to need to test for something specific, i.e. if the shop needs to watch out for acetone, I should test acetone. Of course, if enough of a flammable gas is in the air, it will set it off no matter what, but I should focus on what the danger is for calibrating. + +Based on the resistance chart, I'm going to use a fixed 200K and a 1M pot. Pots are to be avoided, but here we need to calibrate over time. For the response of the v divider, the sensor is not linear, but closer (though not quite) logarithmic. So what I will do, is have to use some math on the micro, and use the formula they give in the Datasheet, to get a logarithmic output that appears linear (figure 5). For my needs, it is good enough. + +\includegraphics[scale=0.8]{../pics/resistances.png} +\captionof{figure}{Application Note resistance table} + +\subsubsection{Fixed resistors} +If these sensors are consistent enough, possibly I could use fixed resistors later. +\subsubsection{Gas Sensor Power Usage} +Rated at 900mW for 7V, so about 150mA (128mA). I know from prior experience these things heat up, so we need plenty of power. + +\subsubsection{PCB Layout} +The gas sensor must be sideways, as there is excessive dust in the shop so, the holes will be on the side. I will do a 90 degree edge mount pcb. + +\subsection{Switcher} +STS1024S6V5 Seems like a fair option for now. Output is 6.5 volts which is enough. Will use a module. Need to make a footprint. + +\subsection{Enclosure} +We need a box that is tall enough to be a cube. Also want square, not rectangular. I plan to have the leds light from the back of the pcb. The pcb will be the top cover / front. The top cover / front will be the box, put on its side, so dust doesn't collect on the leds.

This device is good for a doorway, where the door must be opened in order for people to pass. Putting it in the way of the door ensures that it will activate. It has a distance of at a max 15 feet or 3 meters. It is a laser type tripwire, which means it can be avoided, if someone knows where it is. + +Device was assembled and using the ZMHW Modector source code. This is simply an Arduino sketch with UIPEthernet (to use the ENC28J60) (make sure CS is pin 10 on Uno). For more details see source code. Explaining the details is out of the spec of this doc. Simply put, the ENC28J60 is connected, the Sick sensor black wire is connected to Analog input 1, and a speaker is connected. + +Of importance, Figure 1 shows two things, first off a diode connected in series with the output of the Sick sensor, and also the orange LED on the top of the sensor. The orange led will be green when there is no connection between the diodes and orange when the Diodes (or LEDs) are lined up correctly. When someone moves across the field of their vision, the orange LED will change to green. + + + + + + + + + +\end{document} + diff --git a/ZMHW_Modector/docs/3.tex~ b/ZMHW_Modector/docs/3.tex~ new file mode 100644 index 0000000..01a8b20 --- /dev/null +++ b/ZMHW_Modector/docs/3.tex~ @@ -0,0 +1,35 @@ + +\documentclass[11pt]{article} +%Gummi|065|=) +\usepackage{graphicx} +\usepackage{caption} +\title{\textbf{ZMHW Modector}} +\author{Steak Electronics} +\date{} +\begin{document} + +\maketitle + +\tableofcontents + +\section{Overview} +Making and deploying a Motion Sensor for Zoneminder CCTV software installations.

The orange led will be green when there is no connection between the diodes and orange when the Diodes (or LEDs) are lined up correctly. When someone moves across the field of their vision, the orange LED will change to green.\footnote{This will later become important when installing the IR diode and receiver, as they must be lined up correctly.} +\subsection{Diode on Output of Sick Sensor} +Some IR diode / receiver pairs output a high or low. Some, like the Sick sensor, output a high or low (depending on whether you connect to white or black wire), however they are meant to be connected to a transistor, and thus if you connect it directly to a micro expecting it to go high or low, it will not. Being lazy, and seeking a quick solution, I put a 1N4819 in series with the output of the Sick sensor. +TODO: pictures showing waveforms +\footnote{This is possibly an issue of output impedance, but I will admit, at the time, I didn't bother to check.} + +Using the black wire, it will be normally low and go high when motion is detected (the white wire is the opposite). If you connect to a micro it will fail to go high (why?). If you put a diode on the end in series, it will turn the normally low to a noisy normally low, and sometimes it will go between 2.5-5 volts in spikes. This allows us to use the ADC to read the Sick sensor, and avoid the use of adding a transistor in. The transistor would allow for a digitalRead to be used, but we have plenty of Analog inputs to use, so let's use one of those. + +It's important to line up these sensors. If they are not lined up precisely, they will not get a sync, and the motion detection will fail. + + + + + + + + +\end{document} + diff --git a/ZMHW_Modector/docs/4.tex~ b/ZMHW_Modector/docs/4.tex~ new file mode 100644 index 0000000..16fb94c --- /dev/null +++ b/ZMHW_Modector/docs/4.tex~ @@ -0,0 +1,58 @@ + +\documentclass[11pt]{article} +%Gummi|065|=) +\usepackage{graphicx} +\usepackage{caption} +\title{\textbf{ZMHW Modector}} +\author{Steak Electronics} +\date{} +\begin{document} + +\maketitle + +\tableofcontents + +\section{Overview} +Making and deploying a Motion Sensor for Zoneminder CCTV software installations.

If you connect to a micro it will fail to go high (why?). If you put a diode on the end in series, it will turn the normally low to a noisy normally low, and sometimes it will go between 2.5-5 volts in spikes. This allows us to use the ADC to read the Sick sensor, and avoid the use of adding a transistor in. The transistor would allow for a digitalRead to be used, but we have plenty of Analog inputs to use, so let's use one of those. + +It's important to line up the emitter and receiver. If they are not lined up precisely, they will not get a sync, and the motion detection will fail. Thankfully, the diode outputs more of a cone, and less of a straight line, so some buffer is there.

The HFS-DC06H. This sensor is a combination of an HB100 radio, with a decoding board that will read the signal and output a logic high or low.

This device is good for a doorway, where the door must be opened in order for people to pass. Putting it in the way of the door ensures that it will activate. It has a distance of at a max 15 feet or 3 meters. It is a laser type tripwire, which means it can be avoided, if someone knows where it is. + +Device was assembled and using the ZMHW Modector source code. This is simply an Arduino sketch with UIPEthernet (to use the ENC28J60) (make sure CS is pin 10 on Uno). For more details see source code. Explaining the details is out of the spec of this doc. Simply put, the ENC28J60 is connected, the Sick sensor black wire is connected to Analog input 1, and a speaker is connected. + +\includegraphics[scale=0.4]{../pics/DSCN0207.JPG} +\captionof{figure}{Testing the Sick IR Diode Tripwire } + +Figure 1 shows two things, first off a diode connected in series with the output of the Sick sensor, and also the orange LED on the top of the sensor. The orange led will be green when there is no connection between the diodes and orange when the Diodes (or LEDs) are lined up correctly. When someone moves across the field of their vision, the orange LED will change to green.\footnote{This will later become important when installing the IR diode and receiver, as they must be lined up correctly.} +\subsection{Diode on Output of Sick Sensor instead of Transistor (Hack)} +Some IR diode / receiver pairs output a high or low. Some, like the Sick sensor, output a high or low (depending on whether you connect to white or black wire), however they are meant to be connected to a transistor, and thus if you connect it directly to a micro expecting it to go high or low, it will not. Being lazy, and seeking a quick solution, I put a 1N4819 in series with the output of the Sick sensor. +TODO: pictures showing waveforms +\footnote{This is possibly an issue of output impedance, but I will admit, at the time, I didn't bother to check.} + +Using the black wire, it will be normally low and go high when motion is detected (the white wire is the opposite). If you connect to a micro it will fail to go high (why?). If you put a diode on the end in series, it will turn the normally low to a noisy normally low, and sometimes it will go between 2.5-5 volts in spikes. This allows us to use the ADC to read the Sick sensor, and avoid the use of adding a transistor in. The transistor would allow for a digitalRead to be used, but we have plenty of Analog inputs to use, so let's use one of those. + +It's important to line up the emitter and receiver. If they are not lined up precisely, they will not get a sync, and the motion detection will fail. Thankfully, the diode outputs more of a cone, and less of a straight line, so some buffer is there. When the lights are dark, it is possible to see the red IR emitted if the distance is not too much. + +\subsection{Broken ENC28J60 Module} +During my testing, I suddenly was unable to get an IP address.

This device is good for a doorway, where the door must be opened in order for people to pass. Putting it in the way of the door ensures that it will activate. It has a distance of at a max 15 feet or 3 meters. It is a laser type tripwire, which means it can be avoided, if someone knows where it is. + +Device was assembled and using the ZMHW Modector source code. This is simply an Arduino sketch with UIPEthernet (to use the ENC28J60) (make sure CS is pin 10 on Uno). For more details see source code. Explaining the details is out of the spec of this doc. Simply put, the ENC28J60 is connected, the Sick sensor black wire is connected to Analog input 1, and a speaker is connected. + +\includegraphics[scale=0.4]{../pics/DSCN0207.JPG} +\captionof{figure}{Testing the Sick IR Diode Tripwire } + +Figure 1 shows two things, first off a diode connected in series with the output of the Sick sensor, and also the orange LED on the top of the sensor. The orange led will be green when there is no connection between the diodes and orange when the Diodes (or LEDs) are lined up correctly. When someone moves across the field of their vision, the orange LED will change to green.\footnote{This will later become important when installing the IR diode and receiver, as they must be lined up correctly.} +\subsection{Diode on Output of Sick Sensor instead of Transistor (Hack)} +Some IR diode / receiver pairs output a high or low. Some, like the Sick sensor, output a high or low (depending on whether you connect to white or black wire), however they are meant to be connected to a transistor, and thus if you connect it directly to a micro expecting it to go high or low, it will not. Being lazy, and seeking a quick solution, I put a 1N4819 in series with the output of the Sick sensor. +TODO: pictures showing waveforms +\footnote{This is possibly an issue of output impedance, but I will admit, at the time, I didn't bother to check.} + +Using the black wire, it will be normally low and go high when motion is detected (the white wire is the opposite). If you connect to a micro it will fail to go high (why?). If you put a diode on the end in series, it will turn the normally low to a noisy normally low, and sometimes it will go between 2.5-5 volts in spikes. This allows us to use the ADC to read the Sick sensor, and avoid the use of adding a transistor in. The transistor would allow for a digitalRead to be used, but we have plenty of Analog inputs to use, so let's use one of those. + +It's important to line up the emitter and receiver. If they are not lined up precisely, they will not get a sync, and the motion detection will fail. Thankfully, the diode outputs more of a cone, and less of a straight line, so some buffer is there. When the lights are dark, it is possible to see the red IR emitted if the distance is not too much. + +\subsection{Broken ENC28J60 Module} +During my testing, I suddenly was unable to get an IP address. I checked the testsuite sketches, which didn't work, then began tearing down my setup, testing another Arduino and ENC module. It turned out, the ENC28J60 module failed on me. Make sure to buy backups. + + +\subsection{Installation Log in Pictures} +Here is an overview of what installing this in the wall might look like.
