IR Receiver Diode VS1838B مستقبل الإشاعة تحت الإمراء

The VS1838B is a highly sensitive IR receiver diode engineered to capture infrared remote-control signals with precision and reliable performance. It is optimized for a wide range of remote-control and IR communication applications where dependable signal reception and noise suppression are required.

• 38 kHz carrier frequency: Accurate decoding of standard remote-control protocols for responsive device control.
• Carrier wavelength around 940 nm: Matches common IR LED transmitters to maximize sensitivity.
• Compact package (5.8 mm × 4.8 mm): Easy integration into small PCBs, hobby projects, and consumer devices.
• High signal-to-noise ratio: Precise reception even in environments with competing light sources.
• Operating voltage 5V: Compatible with typical microcontroller circuits and consumer electronics.

The VS1838B incorporates filtering technology that suppresses ambient light interference and reduces false triggers, delivering stable reception across varying lighting conditions. Its 38 kHz standard operating frequency aligns with most household remote controls, simplifying integration into audio equipment, set-top boxes, robotics platforms, and other IR-based communication systems.

Designed for both hobbyists and professional developers, the VS1838B balances sensitivity, noise immunity, and a compact footprint to provide long-term stability and ease of use in projects requiring reliable infrared signal detection.
