KY-022 VS1838B Infrared Sensor Module

KY-022 VS1838B Infrared Sensor Module is a simple yet effective component for receiving infrared signals, commonly used in remote control applications. This module integrates the VS1838B infrared receiver IC, a resistor, and a status LED onto a small PCB. Hobbyists and students often use this module for projects that require a simple way to interface with standard IR remotes, enabling them to build remote-controlled robots, home automation systems, and other interactive electronic devices. Its straightforward 3-pin design makes it incredibly easy to connect to a microcontroller.

Key Features:

• High Sensitivity: Accurately detects infrared signals modulated at 38 kHz, a standard frequency for many commercial remote controls.
• Integrated LED: An onboard LED visually confirms when the module successfully receives an IR signal.
• Simple 3-Pin Interface: Features Ground, VCC, and Signal pins, which simplifies wiring and makes it ideal for breadboard use.
• Wide Operating Voltage: Works reliably with most microcontrollers, supporting a voltage range of 2.7V to 5.5V.
• Good Reception Range: Capable of receiving signals from a distance of up to 18 meters.

Technical Specifications:

• Operating Voltage: 2.7 V to 5.5 V
• Operating Current: 0.4 mA to 1.5 mA
• Reception Distance: Up to 18 meters
• Reception Angle: ±45°
• Carrier Frequency: 38 kHz
• Output Logic: Active Low (Signal pin goes low upon receiving an IR signal)

Mechanical Specifications:

• Module Type: Breakout PCB with soldered components
• Connector: 3-pin male header
• Assembly: Designed for easy insertion into breadboards or use with jumper wires
• Material: FR4 PCB

Dimensions:

• Board Length: ~24.5 mm
• Board Width: ~16 mm
