Object Detection Circuit by using IR sensors (Infrared LEDs)
IR
sensors are of many kinds such as burglar
alarms, TV remote controllers, object counters etc. In this circuit,
IR sensors are used to make an object
detection circuit and a proximity
sensor for path tracking robots.
The working of this is to convey infrared
led light through an IR LED
which is then sensed by the receiving LED.
