Pebbles are designed to specifically only detect human presence and will therefore not respond to the movement of other objects like chairs, vacuum cleaners, etc. It is placed underneath desks, and whist occupancy detection is extremely accurate, it is also completely anonymous and unintrusive.
Most companies overestimate how much office space is really occupied in traditional working environments. The Pebble sensors can help organizations measure occupancy and desk usage, to assist you to decrease rental cost and utilize space more effectively.

Pebbles use an embedded Doppler sensor to measure human presence and have a 600mm diameter 360 degree measurement field that detects through materials such as wooden desktops and seating foam. This means that the detection capability is much higher and more accurate than traditional line-of-sight PIR motion detection devices.
Pebbles are powered by rechargeable batteries, which last 12 to 18 months. Our solutions hub monitors battery levels and users will be notified when Pebbles need to be recharged.
Sensor modules communicate via a BLE mesh network which is closed and securely provisioned. Pebbles always communicate with a Doc which functions as the gateway to delivering data to the Solutions Hub. A common ratio for deployment is 20 to 30 Pebbles to one Doc. The data is shared over a closed Bluetooth mesh network which needs no client connectivity or integration.
