The KY-022 IR receiver module is designed for efficient infrared signal reception for a wide range of electronic projects. Its compact form factor and integrated detection circuitry deliver reliable performance for remote control decoding, sensor interfaces, and other IR-based applications.
Standard operating frequency: 38 kHz for broad compatibility with most IR remotes
Compact footprint: 20mm x 15mm for easy integration into confined spaces
Wide operating voltage: 3.3V to 5V to suit common microcontroller systems
Built-in photodiode and preamplifier for improved sensitivity and reduced noise
Fast response time: under 20 microseconds for prompt signal processing
Compared to other IR receiver modules, the KY-022 provides a balanced compromise between small size and stable performance, making it suitable for both hobbyist and professional uses. The module’s integrated amplifier and tuned photodiode improve the signal-to-noise ratio and help maintain decoding accuracy even in environments with ambient light disturbances. Its straightforward electrical requirements and compatibility with standard microcontroller input pins simplify implementation in remote control, sensor, and signal-detection projects.
