WL-MD-A, wireless IR motion detector is kind of product based on Zigbee wireless technique. Usually, in the range of 6 meters from the IR motion detector, if someone broke into illegally, the infrared ray of human body will be detected in real-time and wireless alarming signal will be sent to the host to realize the monitoring function.

 

WL-MD-A, wireless infrared intrusion detector adopts the Zigbee wireless communication technology, so there is no need of any cable, which enhanced the concealment of product and it won’t be easy damaged in monitoring places.

The Human body’s temperature is constant, and the center wavelength of radiation infrared is 9-10um, the wavelength sensitivity of detect chip embedded in wireless IR motion detector is 0.2-20um. After being enhanced by Philip Neil filter, the IR of human body will be gathered on the infrared sensors. Pyroelectric components are usually embedded in infrared sensors, when there is a change of received infrared radiation temperature, these pyroelectric components will lose charge balance and release charge, after being detected and processed, the alarm signal will be sent out.

 

WL-MD-A, wireless IR motion detector is extensively used in many fields. Because it doesn’t emits radiation, it won’t be detected by routine ways easily. Apart from being used in known as the automatic corridor switch and ATA(anti-theft alarm), it is also extensively used in many monitoring fields.
