hi i want to design a detector to detect smoke there are two ways 1)using ldr(its resistance differes by tensity of light) 2) using smke sensor some say we...
It is depend on the smoke you want to detect as well as accuracy requirement. Photodiode based device might be enough while keeping the price low. Better...
I thought ionization type smoke detectors were the norm these days. All the detectors I have in the house have the little radiation warning sticker on them....
Dear Nick, Recently we have published one paper in Inorganic chemistry journal, ACS. I have attached the same paper. For this I would like to know the sensor...

My goals are to develop a usb based temperature sensor allowing for multiple measurements within a computers environment. I wish to learn about circuit design...
I think this would be more of a firmware and software project rather than hardware. I think, the hardware can be fairly straightforward. * Microcontroller...
Hi, I have debug my circuit for some time and couldnt figure out what isthe problem. I'm not familiar with touch sensor and would reallyappreciate any help...
Colleagues, Sorry, this question is not directly related to sensors. Have anyone seen really short EuroCard connectors in his travels? The shortest ones I've...
Check out the transistors purposes in the circuit. If they work just as a switch or relay, you could use any of them. Based on its datasheet (issued by Advani...
i'm fahmi, student ,i'm using mikrokontroler Atmega 8535 n TGS2610 Sensor for my final project, "Leaking LPG Gas Detector Using Short Messege Service",in this...
Hi Fahmi, the simplest way is to put the detector device in series with a fixed resistor to form a voltage divider. This is shown in the TGS2610 data sheet. ...
As mentioned recently, stable supply and reference is a must. You could use either wheatstone bridge or current-to-voltage converter. I suggest the 2nd...
Hello. I design a project and I need to know how can I do for conditioning signal provide for a photodiode. Do you have some ideas about this? Att Bruno ...
A lot depends on what you are looking for. Are you trying to detect a fast pulse with accurate timing, or high frequency carrier? Are you detecting a feeble...
A CO2 laser might be fun. You could cut steel when you don't need to detect intruders. (We really need more information about your application.) SherpaDoug...
IR LED is enough for simple application, easy modulation, and low power. Gas lasers are for higher power and narrow band. Thermal sources with optical filter...

bros. i m working upon 'automatic room lights ' project, assigned at university.... In which we have to switch 'on' or 'off' the lights of a room for a person...
For good linearity you want to use the photovoltaic mode. Put the diode from ground to the (-) input of a good op-amp, and ground the (+) input. Wrap a...
From what you wrote I would assume they are talking about one of those IR motion detectors used on lighting. They don't generate any IR beam of their own....
