Remote Tester Circuit

By Ashutosh Bhatt

Today we are controlling many appliances with the help of remote like AC, TV or music system. It often happen that remote stops working due to any reason (low battery or any button of remote becomes faulty). Therefore here is the remote tester circuit to test your remote to identify that appliance (TV, AC etc) has problem or your remote is not responding. Advantage of circuit-

1. Based on single sensor.

2. Circuit consumes very less power.

3. Almost every remote can be tested with the help of this circuit as operating frequency of sensor is 38 KHz.

4. High immunity against ambient light.

5. With little modification in the circuit you can use it to control your home appliances with remote.

This remote tester circuit is based on infrared sensor IC TSOP1738. TSOP1738 contains photo detector and preamplifier both in one package. It is a three terminal device. Pin1 is used as ground pin. Pin 2 is for power supply and pin 3 is used for output. Pin diagram of TSOP1738 is shown below. Take care while connecting the TSOP pins as wrong connections may lead to damage of sensor. Following figure shows the pin diagram of TSOP1738.

Assemble the circuit as shown in circuit diagram and apply power supply. When power supply is given LED connected at the output starts blinking. When IR waves from remote fall on the sensor, its output changes to low state. This will turn ON the transistor connected at the output and LED will blink according to the button press on the remote. If this phenomenon happens, it means your remote is working fine. Here R2 and D1 are used to limit the current into the sensor. Do not supply more than 5V directly to pin 2 of TSOP1738 else it will destroy the sensor.
