Effortless proximity detection 

The Wireless Proximity Sensor can detect objects that are removed or placed in front of the sensor. In addition to periodic heartbeats every 15 minutes, the sensor transmits a message when an object is removed or placed in front of the sensor. Data is relayed to the cloud through Cloud Connectors (gateway), where it can be seen in Studio or exported to other services via developer APIs.

How it works

The sensor detects when an object is placed or removed within 0-5 mm from its front. The sensors do not measure the distance to an object; it only measures if an object is present or not within 5 mm.
