EnOcean Wireless People Flow Sensor

Detect people going in and out of a doorway automatically, and in real time

Pressac’s people flow sensors detect when a person walks towards or away (bi-directional) from the sensor. The small sensors are mounted above a single doorway and send a message each time a person enters or exits through the doorway. You can use the data to report people flow in/out of a room in real-time or count how many people have entered or exited a room.

Pressac’s people flow sensor is designed to be mounted above a single doorway to detect the in- and out-flow of a room. USB-powered for easy installation.

Accurate, privacy-compliant monitoring
The people flow sensor uses time of flight technology to detect when a person walks towards or away from it. No cameras. No interference from glass reflections. Fully anonymous.

Access real-time data locally or in the cloud
People flow data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.
