infrared detector circuit using pid20


Posted on Feb 4, 2014

This infrared detector circuit is designed using the PID20 integrated circuit manufactured by Siemens (which converts thermal radiation into electrical impulses), an operational amplifier and a few electronic components. The output signal at pin 3 is compared with a reference voltage equal to half the supply voltage. Reference voltage is taken fro

m the voltage divider R2-R3-R4-R5. When approaching an object warmer than the surrounding environment, or to remove an object colder than the environment, the output voltage increases. Variation of the sensor output will be compared, the IC2a and IC2b, located voltage of 0. 5 V under and over voltage reference respectively. Depending on the output, one of the comparators basculate and activates T1.
