Description
KY-022 Infrared Receiver Sensor Module Detector IR TSOP1838 37.9kHz ESP32 WLED IR
The KY-022 infrared receiver module is a simple device that can be used to detect infrared (IR) signals from a remote control or other IR source. It consists of an infrared receiver, a demodulating circuit, and an output pin.To use the KY-022, you will need to connect it to a microcontroller or other device that can read the output signal from the module. When the KY-022 receives an infrared signal, it will output a digital signal on its output pin. You can then use this signal in your code to trigger an event or perform some other action.
The KY-022 is often used in projects that involve remote control, such as building a remote-controlled robot or adding IR control to a device. It is a low-cost and easy-to-use component that is commonly used in DIY electronics projects.
This IR receiving module uses a built-in infrared dedicated 1838 IC, and can work under 500 lux light intensity
