TSOP 1738 IR Receiver

A TSOP1738 is an IR receiver sensor that is used to receive an output signal from the IR based remote like a TV remote, AC remote, etc. It works on a frequency of 38Khz. It includes a photodetector and preamplifier inside it. It is a low power device that is highly immune to ambient light. When you press any button on an IR remote, the IR remote sends a signal associated with that button at 38KHZ. That is then received by the photodetector inside the sensor and the pre-amplified using a preamplifier. The pre-amplified signal can be further used by the microcontroller to decode the received data from the sensor.
