Kerala-IoT-Challenge

Foxlab Makerspace in association with GTech - Group of Technology Companies in Kerala is launching our prestigious program “Kerala IoT Challenge 2021”, with a vision to mould 100 IoT experts in Kerala, hosting on the µLearn platform. Kerala IoT Challenge is a program designed in 4 levels followed by a hackathon to identify and train quality industry leaders in the IoT domain, while any novice learner can start with layer 1 and others can enter laterally to the desired layer after an evaluation.

About Me

Exp 10 : IR Remote Control Using TSOP

What is an infrared receiver?

The signal from the infrared remote controller is a series of binary pulse code. To avoid the other infrared signal interference during the wireless transmission, the signal is pre-modulated at a specific carrier frequency and then send out by an infrared emission diode. The infrared receiving device needs to filter out other waves and receive signals at that specific frequency and to modulate it back to binary pulse code, known as demodulation.

Working Principle

The built-in receiver converts the light signal it received from the sender into feeble electrical signal. The signal will be amplified by the IC amplifier. After automatic gain control, band-pass filtering, demodulation, wave shaping, it returns to the original code. The code is then input to the code identification circuit by the receiver’s signal output pin.
