Sensors

I would like to know if anyone here at this site has created or seen or heard of using sensors inside or outside the house to warn you of intruders? If you have any information/site/idea on how to go a bouts using sensors in that manner please let me know. Only serious responses welcomed. I am not trying to be funny/sarcastic/ignorant etc , just had this idea that someone somewhere has done this project before. Thanks. AL.

Speed sensor

I have a 60 tooth ferromagnetic ring gear with a speed sensor attached. Each passing of a tooth creates a pulse in the sensor sending a signal to the ecu for calculation of attained rpms. It calculates the interval between the teeth to obtain the rpms, thus determining when to kick in the rev limiter on my 06 polaris ranger XP 4x4. Is it possible or even practical to eliminate every other tooth to "fool" the sensor into a lower rpm reading, and creating higher rpm levels within the motor?

sensors and servos

Hidden Proximity Sensor

Hey guys, I am trying to find a method of creating a hidden proximity sensor that would work similarly to a laser i.e. if the line of sight is broken then an output can be achieved, but without actually using lasers. There are a few problems, the sensor will be in a dark space and will have some smoke blown through the line of sight (lasers would be seen). I want the sensors to be hidden, so they will have to be mounted out of sight, but as they will be used in a relatively open space, i imagine this will mean on the ceiling. This will mean that they will have to detect all the way to the floor, so the range will probably have to be at least 8 feet. Does anybody have any ideas? i'd really appreciate any input. Neal

Selection of presence sensor

Hi guys. For one of my university projects I need to detect the presence of a person in the shower. In order to do that what I have in mind is use a proximity sensor. If the target is in a distance range (let's say 20 to 50 cm) It will assume that the person is in the shower when the distance measure is no longer in this range then it will mean that the person left the shower. I need to detect all the time of the person in the shower (meaning when he/she gets in and then out). I have read a lot of info and forums to properly choose the type of sensor. However I still don't have a clear answer. About the Ultrasonic proximity sensors I know that they are cheap and more accurate by it can be affected by Temperature, humidity and some ambient noise, all of them which happen in a shower. The other option an Infrared one gets affected by lightning conditions and the surface of the target. The last option I checked is a PIR sensor I know it senses Temperature of the target, but I don't know if it will be affected by the running hot water and also is more expensive. In general, I don't know how the running hot water will affect the detection of the person in shower. Also,so again I don't know how this will work. Sorry for the huge amount of  questions, I am a little bit confuse with all the factors to have in mind. I am hoping someone out there can help a lost newbie like me and give me a suggestion. Thanks a lot :)

Sensor Help with Arduino

Hi all! I need help with trying to figure out datasheets. I was digging through my electronics when I found and LM35 sensor. So I looked up the datasheet but I couldn't find out how to convert the analog output to a temperature. I found an i'ble on how to do it but I want to know how to find that information in the datasheet so that next time I get something I'll be able to do it myself. I looked at all the curves and none of them seemed to be temperature vs. voltage. I also looked through the whole first part and couldn't find the multiplier. Also does that multiplier change with the amount of voltage you supply the LM35 with? Say I use 5 volts. Will it give a different reading over 4.5 volts? There's so much technical and complicated data that I don't know what to look for. Here is the link to the datasheet http://www.ti.com/lit/ds/symlink/lm35.pdf Thanks!

CO2 analyzer (sensor)

Dear friends My research topic is about designing a chemical reactor for CO2 capture. I have designed an experimental reactor and I need to measure the concentration of CO2 in the outlet of the reactor. Accordingly, I need a CO2 analyzer (CO2 sensor) that would be able to measure the concentration of CO2 and record it in the computer. I have searched google, but I have not found too many products that can be used in my research. Could you inform me if you know any CO2 analyzer or sensor that meets the following criteria: 1) I need to record the variations in CO2 concentration in short periods of time, for example every 20 sec. The analyzer should have a data acquisition system or can be connected to data logger to record the data in the computer. 2) I need to change the flow rates every time I begin the experiment. The range of flow rate will be between 1 to 5 Lit/min. The flow gas usually contains 25% of CO2. While I appreciate your kind attention, I look forward to hearing from you soon. Best regards Saeb

PIR Sensor troubleshooting

Hello there people of the internets, I'm an electronics newb, hoping someone can help me. I'm trying to trigger a 1.5-3 volt DC motor using a PIR sensor, without using a microcontroller.   I have the PIR sensor's output connected to an npn transmitter which triggers a 5v spdt relay to switch on the motor.  When testing the circuit with an LED, it works perfectly, turning the LED on when motion is detected.   When I swap the LED for the motor, the relay turns on the motor repeatedly every 6 seconds no matter whether there is motion or not. (it also may have killed the relay after about a minute or two) I tried a different circuit, using a transistor as a switch instead of a relay, which also works perfectly with an LED, but when the motor is connected instead, again the motor is turned on every 6 seconds without a care for the PIR output. What could I be doing wrong here?  I'm assuming that perhaps it has something to do with kickback from the motor...maybe? Anybody have any advice?  (Remember, no microcontroller!  As much as I'd love to try my hand at using arduino or the like, I can't afford to use a microcontroller for this particular project.)

Interactive lights with sensors and such

I am currently working of my BFA in sculpture and I have a couple of gallery shows coming up and it would seem that my ideas are bigger than my knowledge base (which is okay by me, but sometimes frustrating). My current work revolves around posthumanism and I am working to blur the lines between human and machine, working with circuitry, xrays, and prosthetics. I have one set of work that I am currently a bit stumped with. I have three copper PCB boards that I am going to etch into circuits, but the lines of the circuits will resemble human faces. Each board has a character: the introvert, the extrovert, and the antagonist. The introvert will be silent, but I want the lights that glow behind it to flicker faster, or get brighter when the viewer nears. Essentially, he is quiet, but has a LED driven anxiety attack when people approach. I did this with a dark sensitive photosensor thinking that the viewers shadows would activate the light. While it worked in my living room, I realized that the gallery lighting would not lend itself to this method. So my next thought was a theremin that had light output instead of sound output. Possible? The next two will make sound and light. The extrovert needs to seek attention. I was hoping to figure out something that would talk back when something is making noise around it. So it would need to pick up the vibrations of someone talking about my work, or possibly even their footsteps, and then begin to "talk back" (lighting up and making noise). Intstead of sensing vibrations I was thinking that proximity might be easier so maybe an IR sensor. (?) The last one hate the second one. I was thinking I might be able to do something like this with a kit I have that allows me to plug one circuit into another, , where I would have it sense the light or sound coming from the extrovert and in turn verbally assault him. However,it is not a definite go, still lots of kinks so I am up for any solutions. I hope this is somewhat coherent to you. If you could give me any leads on where to start, or any places to get good information/products, that would be immensely appreciated. Thanks for your time!

Could anyone point me in the right direction to where I should be looking please and what some of the steps I am going to need to take are please?  In my mind it would work when a blood pressure reading is taken and the monitor shows a reading within the healthy and happy range.
