A simple Remote tester to check all types of Remote hand sets…….
This simple remote tester can be a good tool to check whether a remote hand set is working or not. It uses the commonly available IR sensor TSOP 1738.The IR sensor has a PIN photodiode and an FET signal amplifier enclosed in an Epoxy case.
The sensor requires five volts for its operation and its output is active low. Normally its output gives + 5 volts and goes down to zero when it receives 38 KHz pulsed IR rays. When the remote handset is focused on to the sensor and any one button is pressed, buzzer beeps and LED blinks indicating that the handset is OK. Remote Tester Circuit Diagram
