AM312 PIR Motion Sensor Module 10 Pack Infrared Human Detection Wide Voltage Range DC 2.7V12V Description

Product: 10Pack AM312 Pyroelectric Infrared PIR Motion Sensor Modules Voltage: DC 2.7V to 12V Overview Compact AM312 infrared motion sensor modules designed for reliable human presence detection. Each module uses a pyroelectric infrared element to sense motion and outputs a clear signal for integration into control systems. The wide supply voltage range makes these modules compatible with many low voltage projects and devices. Key benefits Simple presence detection: Detects human movement and provides a direct signal for automation, alerting, or logging without complex programming. Broad compatibility: Operates from DC 2.7V to 12V, fitting a wide range of microcontrollers, control boards, and low voltage circuits. Spacesaving design: Small, lightweight modules are convenient for prototyping and for embedding in compact projects. Batch supply: Ten identical modules in one pack for multisensor setups, development, or replacements. What this product solves Eliminates the need for continuous manual switching by detecting human motion for lighting, alarms, or control logic. Simplifies sensor deployment across multiple locations with a consistent, easytointegrate module. Reduces design complexity by providing a readymade motion sensing module that can be connected to existing electronics. Key attributes Model: AM312 Sensing type: Pyroelectric infrared (PIR) for human motion detection Supply voltage: DC 2.7V to 12V Format: Compact PCB module with integrated sensor element Output: Motion detection signal suitable for direct interfacing with control circuits Performance notes Responsive to human motion and suitable for typical indoor detection tasks. Wide operating voltage improves tolerance to different power sources and systems. Consistent behavior across modules in the pack supports multisensor installations. Typical applications Automated lighting: Turn lights on when motion is detected and off after inactivity to improve convenience and energy use. Security and monitoring: Trigger alarms, cameras, or notifications when movement is detected in a monitored area. Smart home and automation projects: Integrate as an occupancy sensor for HVAC control, room presence detection, or interactive installations. What you get Ten AM312 PIR motion sensor modules ready for connection to low voltage control electronics. Integration tips Mount the module in a stable location with a clear view of the detection area for results. Match supply voltage within the specified DC 2.7V to 12V range and connect the output to appropriate input on your controller or relay circuit. Use identical modules from the pack to ensure uniform sensing behavior across multiple points. This 10pack of AM312 modules provides an easy, consistent way to add human motion detection to prototyping projects, automation systems, and sensor networks.
