Infrared Remote Tester is required to test our TV remotes. This is a simple, low cost and easy to construct Infrared Remote Tester. The tester is build around an easily available infrared receiver module. We are engaged in to manufacturing and supplying Infrared Remote Tester nationwide. About the Circuit :Normally data output pin 3 of IR receiver module is at a high level and as such driver transistor T1 is in cut off state. Whenever the IR receiver module receives a valid (modulated) infrared signal, its data output pin goes low in synchronism with the received infrared bursts. As a result T1 conducts during negative pulse period and the LED blinks to indicate reception of signals from the remote such as TV remote control. A miniature active buzzer is connected at the collector of T1 for audio indication. The advantage of this tester is no false triggering due to the ambient light or electronic ballast operated tube lights. IC1 is a regulator IC used to give 5V regulated DC supply.
