O3-SENSE: Edge Multisensor for temperature, humidity, motion, lighting, and occupancy

The award-winning standalone multisensor **O3® Sense** from Delta Controls uses innovative sensor fusion technology to deliver extremely accurate mapping of indoor environments. By integrating temperature, humidity, motion, sound, light, and occupancy detection into a single device, the O3 leverages machine learning to provide fast, accurate feedback on the monitored space. The O3 is easy to install and can be configured right out of the box using just a smartphone.

Thanks to support for the BACnet, MQTT, and BLE protocols, the O3 Sense is an open-platform IoT device capable of integrating with almost any system.

- Composite temperature, humidity, PIR motion, sound, light, and occupancy sensors combined in a single device
- User feedback via speaker and color LED ring with customizable audio tones and colors
- Dual Ethernet connection for daisy-chaining in large spaces; ensures pass-through communication even during power outages
- Configuration via mobile app
- BLE API for custom app development
