KY-022 Infrared Receiver Module

Description

The IR Receiver Module is a compact and versatile electronic component designed to receive infrared (IR) signals from remote controls and other IR transmitting devices, enabling devices to communicate through IR signals. Equipped with a PIN photodiode and preamplifier IC, the VS1838 IR Receiver Module detects infrared signals at a nominal wavelength of 850 nm. It features a wide 45° detection angle and operates at a carrier frequency of 38KHz, providing a digital output when an IR signal is detected.

The module is compatible with 3.3V and 5V power supplies, making it suitable for various applications. In infrared communication systems, when an infrared signal is transmitted from a remote control or another IR device, the module detects the IR pulses and converts them into electrical signals. Microcontrollers or other electronic circuits can then process these electrical signals to trigger specific actions or commands.

Simple to use, the module requires only ground and Vcc connections. Its output pin is normally HIGH, but upon receiving an IR signal, it pulses LOW, and the onboard LED flashes to indicate signal reception. The IR Receiver Module boasts high sensitivity, ensuring adequate reception of IR signals even from a distance. Its wide frequency range enables it to work with different IR protocols, making it a versatile choice for various IR communication applications.
