The Milesight WS202 combines a PIR motion detection with brightness measurement in one compact sensor.

Add to Quote


The Milesight WS202 light control sensor is ideal for smart buildings and offices. Combining motion and light sensors in one, the WS202 light control sensor can be used alongside an automatic lighting control system.

With an ultra wide detection range of up to 8m distance, 120° horizontal and 100° vertical, one sensor can cover a wide area.

Featuring a compact form factor, this wireless light control sensor is simple to install and can be used to automate alarms for activity in unoccupied areas or trigger other sensors or appliances such as automatic lighting systems to power up.

Data collected is transmitted to a connected LoRaWAN® gateway and can then be visualised and remotely managed by the Milesight IoT Cloud Solution.
