Microwave sensors generate an electromagnetic (RF) field, creating an invisible volumetric detection zone. When some motion occurs within the detection zone, changes to the field are registered and the attached load is activated. The BS-MV2102 sensor is easy to install, provide high probability of detection, low nuisance alarms and resistive to natural elements like sudden gusts of wind, dust, temperature extremes. It offers benefits in safety and security, energy management, hospitality and true ‘hands-free’ switching convenience in wide range of applications. The output of this sensor is <0.2mW which is just 1/5000^th of the transmitted power of a mobile phone or a microwave oven which makes its usage very safe even for children.
