The Steinel HPD3 KNX Presence Detector is an innovative, surface-mounted sensor designed for professional indoor environments such as conference rooms, open-plan offices, lecture halls, and production facilities. Using high-precision optical sensor technology, the HPD3 detects, counts, and locates individuals in real-time, monitoring up to 5 independently configurable zones. The detector’s environmental sensors measure key factors like temperature, humidity, CO2, and VOC levels, ensuring optimal control over air quality and comfort.

The HPD3 integrates seamlessly with KNX systems, offering intelligent automation for lighting, HVAC, and environmental systems. In addition to KNX, it supports IoT connectivity via REST API, MQTT, and BacNet, enabling integration with smart building platforms. The surface-mounted design makes it ideal for both retrofitting and new installations, and its robust communication features ensure encrypted data transmission.
