There are various applications of IR sensors such as TV remote controllers, burglar alarms and object counters. Here we have used IR sensors (infrared LEDs) to make an object-detection circuit and ...

Working of PIR Sensor with PIC Microcontroller: This project does not have any complicated hardware setup, we are again using the same PIC Microcontroller board (as shown below) which we have created ...

This circuit could probably be rebuilt for cheaper using op amps and maybe 555 timers for the motor PWM but this felt easier Using a transistor to turn on and off the LEDs makes them able to calibrate ...
