Proximity Detector Using TLC272
This proximity detector circuit is designed using a temperature sensor and TLC272 op amp. The temperature sensor can react to any heat generated by body heat.
Proximity Detector Using TLC272 Circuit Diagram:
The sensor used in this TLC272 proximity detector circuit has a sensitive surface which was divided in two, so that it can sense if the heat source is coming from the left or right. Indication for cold objects will be exactly opposite of the warm objects. IC1b form a symmetrical power circuit. Terminal "s" is the sensor output. Signal over the "s" will be amplified in IC1a, with a gain factor of 70, before being delivered to the output detector.
