FAQ
A: What affects the reception distance of an infrared receiver module?
Q: The reception distance depends primarily on four key factors: transmitter power output (affecting signal strength up to 18 meters), environmental conditions (optimal temperature -25°C to +85°C, humidity <80%), physical obstacles (which can reduce the signal by 5-90% depending on material), and ambient light conditions. For best performance, maintain a direct line of sight between transmitter and receiver, avoid strong sunlight exposure, and keep fluorescent lights at least 1 meter away from the sensor.
A: How to improve signal reliability of IR infrared sensors?
Q: Signal reliability can be optimized through proper installation and maintenance. Mount the receiver at 1.5-2 meters height within ±45 degrees angle, ensure stable power supply (3.3V/5V with <100mV ripple), implement proper grounding with a star topology, and use appropriate shielding against interference. Adding decoupling capacitors (0.1μF) near the VCC pin and maintaining a clear line of sight is essential for optimal performance.
A: What causes reception failures in IR receiver modules?
Q: Reception failures typically result from four main issues: power supply problems (voltage fluctuations or current below 1.5mA), frequency mismatch (deviation from 38kHz ±7% standard), environmental interference (from fluorescent lights, sunlight, or electronic equipment), and physical misalignment. Regular maintenance, proper shielding, secure mounting, and ensuring a stable power supply can prevent most reception failures.

Infrared(IR) receiver, also known as infrared receiver module and infrared remote control receiver, referred to as IRM, is an IC infrared light receiving element, the optical diode and special instruction set integrated circuit (ASIC) combined and packaged products. So far, the infrared receiver for remote control is still widely used in consumer electronics products, such as air conditioners, televisions, set-top boxes, remote control fans, etc. The infrared receiver is mainly composed of four parts: built-in PIN diode(PD) and preamplifier(IC), bracket and colloids (pigment, epoxy ). The main function of PD is to receive the infrared signal transmitted by the transmitter; IC is the CPU of the IR receiver, mainly composed of silicon crystal core circuit, the main functions are amplification, limiting, filtering and decoding. Working principle: Infrared receiver can generally receive 850nm ~ 1100nm band of infrared light, which is mainly to receive 940nm infrared light. After the PIN diode monitors the infrared signal, it is converted into an electrical signal, which is processed by the amplifier, limiter, bandpass filter, etc., and finally the signal is restored to the signal waveform at the transmitting end by the decoder, and is output to the control device through the signal output pin of the receiving head, so as to realize the control of the device.
