DC 4.5-20V Pyroelectric Human Body Infrared Motion Sensor Module Switch Light

The Pyroelectric Human Body Infrared Motion Sensor Module Switch Light is a compact and easy-to-install device that can be used to detect human presence and trigger a variety of actions, such as turning on lights or sounding an alarm. The sensor is based on pyroelectric technology, which means that it can detect changes in infrared radiation, which is emitted by all living beings.

Product Features:

* Detects human presence within a 3-7 meter range * Adjustable sensitivity to avoid false triggers * 4.5-20V operating voltage * 500mA load capacity * 3-pin JST connector for easy installation * Small and compact design for easy mounting

Benefits:

* Suitable for a wide range of applications, such as home security, office automation, and industrial control * Convenient and hands-free operation * Reduces energy consumption by automatically turning off lights when no one is present * Enhances security by sounding an alarm in the event of unauthorized entry

Key Usage Points:

* Installation is a breeze with the included 3-pin JST connector. Simply connect the sensor to a power source and the load you want to control. * The adjustable sensitivity allows you to tailor the sensor to your specific needs, reducing the likelihood of false triggers. * The durable construction ensures that the sensor can withstand the rigors of everyday use. * Wide voltage range (4.5-20V) makes it compatible with most power sources. * Blue LED indicator provides visual confirmation of the sensor's status.
