Occupancy Sensors

BigSense Occupancy Sensors are quality, energy saving switches for enhanced control in the home. Our complete line of motion sensors deliver energy savings to help counter rising utility rates, along with fresh ideas to ensure optimal safety.Our convenient and dependable motion sensor solutions do the work for you, making energy savings entirely automatic.

The BS-MV series of sensors are extremely sensitive and reliable options for motion detection from BigSense. BS-MV2102 Microwave Motion Sensor Switch is an energy saving field-proven product ideal for home and commercial uses.


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 1/5000th of the transmitted power of a mobile phone or a microwave oven which makes its usage very safe even for children.
