Motion Sensors

BigSense Motion 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-C series are highly reliable, state-of-the-art passive infrared motion sensor switches from Big Sense. BS-C0023 is an outdoor  Passive Infrared Motion Sensor Switch ideal for home and commercial uses.


Passive Infrared Sensors (or PIR Sensors) allows for motion sensing, almost always detect motion of humans moving across its sensing zones. They detect motion by sensing the heat generated by a moving body. The BS-C0023 sensor is easy to install, rugged and economical and comes with IP44 rating for outdoor use.

The sensor unit is designed to monitor motion within the field of its view and activate an electrical load such as a lamp, in response to that movement. It offers benefits in safety and security, energy management, hospitality and true ‘hands-free’ switching convenience in wide range of applications.
