IR Infrared Transmitter and Receiver Sensor Module 38kHz for Arduino

Product Description

The IR Infrared Transmitter and 38kHz Receiver Sensor Module is a compact and reliable module designed for Arduino, ESP32, Raspberry Pi, and other microcontroller platforms.

This kit allows you to send and receive infrared signals, making it ideal for remote control systems, obstacle detection, wireless data transmission, and DIY electronics projects.

The infrared transmitter module emits IR signals at a central wavelength of 850–940nm with a range of up to 1.3 meters at 5V, while the receiver sensor module detects signals at 38kHz, commonly used in TV remotes and IR communication devices.
