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 also a proximity sensor for path-tracking robots. The basic idea is to transmit the
infrared light through an IR LED, which is then reflected by any obstacle ahead and sensed by the
receiving LED [7].
