Generic VS1838B IR Remote Control Receiver – Pack of 2
The VS1838B is a through-hole infrared receiver module designed for remote control and IR communication systems. It operates from 2.5V to 5.5V DC, making it compatible with 3.3V and 5V logic systems like Arduino and Raspberry Pi, and demodulates 38kHz carrier signals for reliable digital output.
Features
- Integrated photodetector and preamplifier for simplified circuit design
- Demodulates 38kHz carrier frequency with built-in IR filter for ambient light rejection
- Wide operating voltage range (2.5V–5.5V DC) for 3.3V/5V microcontroller compatibility
- Supports common IR remote protocols including NEC and RC5
- Active-low digital output for direct interfacing with TTL/CMOS logic inputs

The VS1838B IR receiver is a self-contained module that integrates a silicon photodiode, a 38kHz bandpass filter, and a preamplifier/demodulator IC into a single epoxy package. This design directly converts modulated infrared light pulses into clean, active-low digital logic signals, eliminating the need for external filtering and amplification circuitry. The built-in IR filter provides excellent suppression of visible light and electrical noise, ensuring stable performance in varied ambient lighting conditions.
Its wide supply voltage range and TTL/CMOS-compatible output make it a versatile drop-in component for microcontroller-based projects. The module is engineered for reliable reception of standard IR remote control signals at typical distances of 8 to 10 meters, providing a robust foundation for home automation, appliance control, and DIY IR communication systems.
