IR receiver and transmitter

High‑Performance IR Receiver/Transmitter Module for Reliable Wireless Control

This compact IR module integrates a precision receiver and transmitter in a single 2.54 mm DIP package, enabling bidirectional infrared communication with minimal PCB footprint. It operates at the standard 38 kHz carrier, providing robust data integrity across a range of manufacturers’ protocols (NEC, Sony SIRC, RC5/6, and On‑Off). The module offers automatic carrier suppression, modulation depth control, and a low‑power standby mode, making it ideal for portable consumer devices and embedded control systems.

Equipped with a built‑in demodulator and programmable threshold, the module delivers higher sensitivity than typical off‑the‑shelf receivers, allowing reliable operation up to 10 m in optimal conditions. The transmitter side supports full‑wave carrier modulation, and both interfaces are compatible with standard UART‑style control, simplifying firmware integration.

• Frequency Range: 38 kHz ±5 % (carrier)
• Displayable Sensitivity: > -80 dBm (typical)
• Data Throughput: 1 Mbps (raw) ≈ 300 bit/s (modem‑encoded)
• Common Use Case: Infrared remote control for home‑automation appliances, automotive climate control systems, and low‑energy consumer electronics.
