O3 Sense, Standalone Multisensor, Configurable

Delta Controls’ award-winning O3® Sense standalone multisensor uses industry-leading sensor fusion technology to deliver the most accurate view of an interior space available on the market.

Integrating temperature, humidity, motion, sound, and light-sensing in a single device, the O3 uses machine learning to provide fast, accurate feedback on the monitored space.

The O3 is easy to install and can be configured out of the box with just a smartphone.

Application

With support for BACnet, MQTT, and BLE protocols, the O3 Sense is an open platform IoT device that can integrate with almost any system.

Features
