상품 특징

• This passive infrared sensor module detects changes in infrared radiation caused by movement of people or animals within its sensing range. It converts infrared signal variation into a digital output suitable for motion detection applications.
• Adjustable sensitivity and output delay time are provided through onboard potentiometers. Users can configure detection distance and signal duration to match different application requirements and environmental conditions.
• Operates with a DC supply voltage from 3.3V to 5V, allowing direct connection to common microcontroller platforms without additional voltage conversion. The digital output can be read directly by GPIO input pins.
• Uses a Fresnel lens to enhance detection coverage and improve sensitivity to motion within the field of view. The sensor provides stable operation with low power consumption during standby and active states.
• Compact PCB design with clearly labeled VCC, GND, and OUT pins simplifies wiring and installation. Suitable for embedded electronics projects, motion-triggered control systems, and experimental development environments.
