The KY-022 Infrared Receiver Module is designed for detecting IR signals within the 700nm to 1mm wavelength range, making it ideal for use in robotics and remote control systems. It operates on a low input voltage of 3.3V to 5V.

When the sensor detects an IR signal, the data pin outputs a HIGH signal; when no signal is detected, it remains LOW. The onboard LED indicator lights up when the sensor is triggered, providing a clear visual cue of signal reception. This module is perfect for integrating IR-based communication into DIY electronics and automation projects.
