Gelidus Research AC Powered mmWave Presence Sensor

Description

This Gelidus Research AC powered mmWave presence sensor provisions:

• • Highly accurate room occupancy detection.
  • Unsurpassed sensitivity and micro motion still detection.
  • By far the best currently available ESPHome presence sensors.
  • Presence detection up to 9 meters away.
  • 16 gate signal detection slots, each gate is configurable for motion and still sensitivity.
  • Configurable min/max gate range.
  • Configurable binary presence output.
  • Easy deployment to any available receptacle.
  • Uses only one AC plug socket.

Hardware:

• • Compact 40 x 80 mm PCB
  • 4 Pin ESP programming header (3.3v  only)

Software:

The Gelidus Research AC powered mmWave presence sensor is designed to run on ESPHome frameworks. ESPHome integration with Home Assistant (HA) is ideal for providing a rich user interface. Adding the GRPS1 mmWave presence sensor to ESPHome and HA is easy using the preinstalled captive portal. Using any tablet or phone that identifies a captive portal you can link up the module without any serial firmware programming hassle’s. Once connected to your WIFI network it’s strait forward with HA integration.

Safety:

Never operate the  Gelidus Research AC powered mmWave sensor board without a protective enclosure, it will expose dangerous potential contact with your AC mains supply. We can supply a safety enclosure or you can download our 3D printable STL files for DIY projects.
