Product Details
＋
The VS1838B is an integrated infrared (IR) receiver module designed for remote control systems. It is widely used in consumer electronics for receiving and demodulating infrared signals from a remote control. The module integrates an infrared sensor and a demodulator, making it easy to interface with microcontrollers and other digital systems.
High Sensitivity: Capable of receiving signals over a long distance.
Low Power Consumption: Suitable for battery-operated devices.
Automatic Gain Control (AGC): Ensures stable reception under different lighting conditions.
Noise Suppression: Built-in noise suppression to prevent false triggering.
Compact Size: The small form factor makes it easy to integrate into various designs.
Standard Modulation Frequency: Usually operates at 38kHz, which is standard for most IR remote controls.
Home Automation: Integrated into systems for controlling lights, fans, and other appliances via IR remotes.
Key Features:
Wide Supply Voltage Range: Operates typically between 2.7V and 5.5V.High Sensitivity: Capable of receiving signals over a long distance.
