infrared temperature sensor
Hi.
Im working on a project where I need to incorporate an infrared temperature sensor (ZTP-135SR). The datasheet from general electrics is very spartane in information. On the sensor there are four wires - A thermistor, a thermopile and a ground wire for both the thermistor and the thermopile.
I have been searching everywhere I can think of to get information on how to connect the device. Im using a pic 16f873a with an ina128p instrumental amplifier.
As far as I can understand the thermistor is there to compensate for the ambient temperature, but how do I connect it?`
If i just connect the thermopile to the instrumental amplifier I get readings, but they vary too much over time to be ok.
If anyone out there has had experience with hooking up an infrared sensor to a pic processor I would very much apriciate any guidance you can give me.
Thanks in advance
