Infrared photodetector module with remote control

The set of this module includes: a remote control with infrared radiation, an IR receiver, an LED and adapters for connecting to the Arduino board. The kit is suitable for both experienced arduists and beginner radio amateurs in the Arduino field.

A module with an infrared receiver designed with an IR sensor (TL1838) and an LED that indicates the reception of a signal from the remote control. The TL1838 sensor can only operate at a signal frequency of 38 kHz. Because of this, it tends to ignore other light noise.

The module is connected to Arduino or other microprocessor devices using a serial I2C interface in the form of a J1 connector (VCC, GND, SIGNAL). The VCC and GND outputs are required to supply a voltage of 5 V, and the signal from the sensor to the Arduino microcontroller is transmitted through the SIGNAL output.

The IR remote control operates at a frequency of 38 kHz and can transmit a signal at a distance of up to 8 meters. There are 17 isolated buttons on the remote control for comfortable control of devices of varying complexity. When the button is pressed, a signal is generated, which is encoded into infrared radiation, then the signal is again encoded into a packet of successive pulses with a certain frequency. After receiving the sequence, the data is demodulated and the information is sent to the microcontroller.

For further work with this set, you need to download the library for the Arduino IDE, and then install it.
