Infrared Waterproof Beam Sensor – Single Beam, 20m Range
Infrared Waterproof Beam Sensor – Single Beam, 20m Detection Range
The Single Infrared Waterproof Beam Sensor is an active infrared detector designed for outdoor perimeter protection, gate automation, and object detection. It consists of a paired transmitter and receiver that create an invisible infrared beam; when the beam is interrupted, the output relay triggers. Its IP65-rated waterproof housing ensures reliable operation in rain, dust, and harsh sunlight, making it a durable choice for Indian outdoor conditions.

Compatibility
With its relay output (dry contact), this sensor works with any microcontroller capable of reading a digital input, including Arduino, Raspberry Pi, ESP32, and STM32 boards. It can also interface directly with PLCs or traditional alarm panels that accept 12-24V DC triggers. The relay supports up to 1A at 30V DC, so it can switch small loads directly.
Wiring Notes
The transmitter and receiver each have a simple 4-wire cable: red (12-24V+), black (ground), green (relay common), and white (relay normally open or normally closed). For a secure trigger, connect green and white to your input with an external pull-up resistor if using a 3.3V logic board. Ensure both units share a common ground for reference.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the relay output can be connected directly to any Arduino digital input pin using a pull-up resistor. When the beam is interrupted, the relay toggles and the pin state changes.
Can it operate accurately in heavy rain?
Yes, the IP65 waterproof housing is designed for outdoor use in rain. The infrared beam is modulated and filtered to reduce false triggers from rain or fog, though range may slightly reduce in extreme downpours.
What is the maximum functional distance between emitter and receiver?
The sensor reliably detects interruptions up to 20 meters in clear outdoor conditions. For indoor use, the range may extend slightly further, but alignment must be precise.
