PIR Motion Detector Sensor Module for reliable motion detection in security, lighting, and automation systems Description This compact PIR motion detector uses Passive Infrared technology to detect changes in thermal radiation caused by people and animals. Its small size and simple electrical interface make it easy to integrate into a wide range of projects and systems. Sensitivity and time delay settings are adjustable to suit different environments and detection requirements. Key benefits Accurate motion sensing for people and animals using Passive Infrared detection. Energy saving by activating lights or systems only when motion is present. Easy integration with control electronics that operate at 3.3 to 5 volts DC. Adjustable sensitivity and time delay allow tuning for specific locations and reduce false triggers. Compact size fits into tight spaces and custom enclosures. Main features Detection range: typically 5 to 7 meters (16 to 23 feet). Detection angle: typically 120 degrees. Operating voltage: typically 3.3 to 5 volts DC. Sensitivity adjustment: onboard control for changing sensitivity to improve detection accuracy. Simple signal output compatible with common control circuits and logiclevel inputs. Compatibility and performance Designed to work with microcontrollers, lighting controllers, alarm panels, and other control systems that accept a logiclevel motion signal at 3.3 to 5 V. Small footprint and straightforward wiring simplify installation in retrofit or designs. Effective for indoor and sheltered outdoor locations where PIR sensing is appropriate. Use scenarios Automated lighting: trigger hallway or stair lighting when a person enters, reducing energy use while improving convenience. Security detection: detect movement inside rooms or entryways to activate alarms, cameras, or recording systems. Smart home automation: integrate with control systems to run scenes when presence is detected, such as turning on ventilation, starting routines, or notifying occupants. This PIR Motion Detector Sensor Module provides dependable, adjustable motion detection for a variety of practical applications while remaining easy to install and tune for specific needs.
