This wired dual passive infrared (PIR) motion detector is designed for seamless integration into existing home alarm systems or as an occupancy sensor for automated lighting and HVAC control. The sensor uses two independent PIR elements to reduce false triggers caused by small animals or environmental changes, while its hardwired connection ensures stable, uninterrupted operation without battery concerns. The housing is constructed from durable, impact-resistant ABS plastic with a subtle matte finish that resists scratches and discoloration over time. The internal circuitry features a high-quality relay rated for 30VDC/0.5A, ensuring reliable switching for most alarm panels and lighting controllers. Each unit undergoes individual testing for sensitivity consistency and response time, with a typical detection range of 12 meters (40 feet) across a 110-degree wide-angle lens. The compact form factor (approximately 3.5 x 2.5 x 1.8 inches) allows easy mounting on walls or corners using the provided screws and anchors.

Operationally, the sensor delivers a clean digital output signal (normally closed contact) upon motion detection, with an adjustable retrigger delay from 2 seconds to 30 seconds via a small trimmer potentiometer inside the housing. Power is supplied directly from the existing system (9–24VDC or 12–24VAC), making it compatible with most third-party alarm panels, home automation controllers, and smart hubs. The lens is made of high-transmittance Fresnel material optimized for human body infrared absorption, providing consistent detection even under varying ambient temperature conditions. The cost is very affordable, making it an accessible upgrade for expanding detection zones in an existing wired alarm system or adding occupancy-based automation to lights, fans, or security cameras. Its straightforward three-wire connection (positive, negative, and signal) simplifies installation for both DIY enthusiasts and professional integrators. The product is built with reliable soldering and double-sided PCB construction to withstand typical residential and commercial environments. Priced at just $2.00, this motion detector offers exceptional value for those needing a cost-effective, dependable occupancy or intruder detection solution. It works effectively in hallways, rooms, garages, and storage areas where a hardwired sensor is preferred over wireless alternatives. The dual-PIR design enhances immunity to sudden temperature changes, reducing false alarms from heating vents or sunlight.
