SKU: SEN185-KL
The Senvolon Presence Sensor KL combines 24 GHz radar technology for motion and presence detection (up to 6m) with integrated measurement of temperature, humidity, and air pressure. Up to three zones can be set up to precisely locate objects in the room. An integrated siren can be easily controlled for monitoring scenarios. The sensor is Smart Home compatible via MQTT (Home Assistant, ioBroker) and can be operated locally without a mandatory cloud connection. Includes 3-year warranty and free updates. The Senvolon Presence Detector KL is set up in a few steps via a web app, can be flexibly mounted on the ceiling or wall, and only requires sufficient Wi-Fi coverage for initial setup.

The Senvolon presence sensor monitors rooms reliably, precisely, and discreetly. Thanks to modern mmWave radar technology, the sensor detects not only motion but also stationary presence, meaning minimal movements such as breathing or small body movements. This makes it fundamentally different from conventional PIR motion detectors and makes it ideal for smart-controlled indoor spaces.

FAQ
Answers to frequently asked questions.
We grant a three-year warranty on all our products. This covers manufacturing and material defects.
The Senvolon presence sensor uses RADAR technology (24 GHz to 60 GHz), which sets it apart from conventional infrared sensors. PIR sensors only register motion (e.g. walking), while 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) stay active as long as a person is in the room.
Typical application scenarios are presence monitoring and controlling lighting and climate in:
The presence sensor KL MZ detects up to three people. The other variants are primarily optimized for monitoring a single room. These provide data on the most recently detected person.
