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.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e20 meters (outdoor)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e12-24V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eRelay (NO\/NC dry contact)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e≤10ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWaterproof Rating\u003c\/td\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Draw\u003c\/td\u003e\n\u003ctd\u003e≤50mA per unit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAutomatic gate opener safety edge alternative\u003c\/li\u003e\n\u003cli\u003eIntruder alert for boundary walls or fences\u003c\/li\u003e\n\u003cli\u003eVisitor counter for event entry points\u003c\/li\u003e\n\u003cli\u003eGarage vehicle detection for automated lighting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eWith 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.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery 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.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan it operate accurately in heavy rain?\u003c\/summary\u003e\u003cp\u003eYes, 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.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat is the maximum functional distance between emitter and receiver?\u003c\/summary\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
