Counting Proximity Sensor


The Wireless Counting Proximity Sensor can detect objects that are removed or placed in front of the sensor. An internal counter is incremented each time status is changed, and the cloud server is updated with the count number at periodic intervals. Wireless messages are sent via SecureDataShot technology to the Cloud Connector (Gateway). The Cloud Connector relays the information onward to the cloud server.

The Wireless Counting Proximity Sensor uses Heartbeat Interval (HBI) to transmit a message notifying the system that it is present and operational, which can be set to 15 min, 30 min, 45 min, or 60 min. 

An immediate message is transmitted if the sensor is touched, allowing real-time sensor testing.
