SKU: SEN182
Thanks to radar technology, the Senvolon presence sensor with WLAN provides true presence detection up to 6 m. Unlike normal motion detectors, it not only detects movement but also when you are sitting or lying still. Up to three zones can be set up to precisely locate people in the room. An integrated siren can be easily controlled for monitoring scenarios. The sensor can be seamlessly integrated into smart home systems like Home Assistant, ioBroker, Node-RED, and OpenHAB via MQTT. The Senvolon WLAN presence and motion sensor is set up in a few steps via a web app, can be flexibly mounted on the ceiling or wall, and only requires sufficient WLAN coverage for operation.

The Senvolon presence detector monitors rooms reliably, precisely and discreetly. Thanks to modern mmWave radar technology, the sensor detects not only movement, but also stationary presence – i.e. minimal movements such as breathing or small body movements. This fundamentally distinguishes it from conventional PIR motion detectors and makes it ideal for smartly controlled interiors.

FAQ
Answers to frequently asked questions.
We offer a three-year warranty on all our products. This covers manufacturing and material defects.
The Senvolon presence detector uses RADAR technology (24 GHz to 60 GHz), which distinguishes it from conventional infrared sensors. PIR sensors only register movement (e.g., walking), whereas our RADAR sensor also detects motionless presence (e.g., a person reading or sleeping). It registers the smallest movements, such as breathing, ensuring that automated processes (like lighting or heating) remain active as long as a person is in the room.
Typical application scenarios include presence monitoring and lighting and climate control in:
The presence detector KL MZ detects up to three people. The other variants are primarily optimized for monitoring a single room. These provide data on the last person detected.
