Wireless People Flow Sensor – Pressac

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

  • Detect real-time entry/exit – Detect when a person walks towards or away (bi-directional) from the sensor
  • Determine the number of people in a space – Count the flow in and out of a space
  • Track space usage over time – Monitor space utilisation over time to make better planning decisions

How our people flow sensors work

Our wireless people flow sensors detect when a person walks towards or away (bi-directional) from the sensor, enabling you to count the in- and out-flow and determine the number of people in a space. The small, battery-powered sensors are mounted overhead above a doorway to report people in/out in real time.


  • Small, discreet sensors simply stick to the ceiling
  • Time-of-flight sensor detects people and the direction of movement. Detects real-time people flow in/out for any single-occupant doorway
  • Privacy and GDPR compliant: sensors only detect people movement. No cameras. Fully anonymous
  • Automatically calibrates to its installed height. Comes with an integrated spirit level to ensure a perfect installation
  • Power-saving technology: ultra-low power PIR sensor detects motion to ‘wake-up’ flow sensor when needed. Battery life typically up to one year. Mains-powered variant available
  • Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
