This project integrates infrared control for managing a television, air conditioner, and lighting system into a unified solution using a KY-022 IR receiver and an IR emitter based on an ESP32. By ...

Two communication links consisting of IR and RF are being used by this remote control which is subdivided into three parts as separate boards including RF transmitter, IR transmitter, and IR/RF ...

This project implements an IR signal transmitter and decoder using the TM4C123GXL (Tiva-C) microcontroller. It sends NEC protocol IR signals using a hand-soldered IR LED circuit and receives IR codes ...

This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...

Abstract: To save time and the expense, a preliminary optical link can be constructed with a white-light AC LED and an IR receiver module. It is not easy to develop a matching optical receiver for a ...
