Product Description

In this circuit, microcontroller AT89C52 counts and shows on an LCD the number of interruption made between IR transmitter and receiver. The IR transmitter (IR LED) generates 38 KHz frequency from 555 timer . At receiver this frequency is sensed by IR receiver IC TSOP 1738. The interruptions generate pulses which are counted by the microcontroller and then display the counts (number of interruption) on LCD.
