Playing With Ir Sensors

Description

ABSTRACT

There are various applications of IR sensors such as TV remote controllers, burglar alarms and object counters. In this work, IR sensors (infrared LEDs) was used 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 an obstacle ahead and sensed by the receiving LED.

On receiving the light, the sensing LED develops a voltage difference across its leads. However, this voltage produces a very weak electrical signal. Therefore we have used an operational amplifier (op-amp) for accurate detection of the object
