Delta Controls O3 Sensor Hub: Intelligent Room Automation

Introducing the O3 Sensor Hub

The O3 Sensor Hub is a new product from Delta Controls, designed for intelligent room automation. It embodies the philosophy of 'Think. Sense. Speak.' and offers advanced sensor technology for total room integration.

Key Features:

• Like a thermostat, but better.
• Breakthrough sensor fusion.
• Breakthrough experience.
• Connects to O3 CPU.
• Ceiling mount design.

What is the O3 Sensor Hub?

The O3 Sensor Hub is the intelligent heart of room automation. It is a new product that integrates multiple functions into a single device.

Key Capabilities:

• Think: Sensor Fusion, Instant Occupancy, Activity Based Control, Programmable O3 CPU.
• Sense: Measures Temperature (IR + Thermistor), Occupancy (PIR + Sound), Light Intensity + Color, Humidity, and utilizes Enocean technology. It acts as one sensor for HVAC, Lighting, and Access.
• Speak: Can Play Sounds, activate a Color Ring, and interact with the Mobile App.

Sensor Fusion Explained

Temperature Sensing

The O3 Sensor Hub monitors room temperature at occupant height (approximately 1m/3ft from the floor) using a sophisticated algorithm that combines readings from three internal sensors. Two are traditional temperature sensors measuring air temperature at ceiling level. The third is an infrared sensor that measures a wide area directly beneath the hub, covering a diameter roughly equivalent to its mounting height. This data, combined with machine learning and Kalman filtering, models the temperature experienced by occupants over time, ensuring accuracy.

Data Visualization: A graph shows temperature readings over time, illustrating the composite, IR + Thermistor, and estimated room temperatures, highlighting the accuracy of the system.

Occupancy Sensing

The O3 Sensor Hub uses three sensors for occupancy detection: PIR for motion, a microphone for sound, and IR for heat signatures (indicating people). Machine learning is employed to refine these readings. The PIR sensor is the primary trigger for occupancy. Sound is considered only after initial occupancy is detected to confirm and maintain the 'latched' state. Ambient noise is filtered out to prevent false triggers.

Data Visualization: A series of graphs depict motion detection, sound levels, and IR heat spikes over time, showing how these inputs are processed to determine occupancy.

Location and Wireless Capabilities

Optimal Placement

For best performance, the O3 Sensor Hub should be located:

• Closer to occupants.
• Away from indirect sunlight.
• With a clear radio antenna path.
• In locations that allow easy movement of walls or equipment.
• Avoiding 'wall acne' (multiple devices cluttering walls).

Considerations for placement include occupancy, tamper avoidance, suitability for open office cubicles, and the choice between T-bar ceiling or wall installation.

Wireless Technology

The O3 Sensor Hub supports wireless communication through technologies like Enocean, enabling sensing and control devices, and is great for retrofits. It also integrates with IR Blasters for similar applications. The system is designed for easy integration and flexibility.

O3 App and User Experience

The O3 App enhances the user experience by providing:

• Room Location: Hubs know when you are nearby.
• Easy Interface: A user-friendly mobile application.
• Activity Control: Manage lighting, blind positions, and temperature setpoints through one-touch controls.
• Customization: Program custom activities rather than using pre-set 'canned' options.
• Re-usability: Activities are stored in EWEB and can be created once and used in multiple rooms.
• Explicit Control: Directly control room settings.
• Room Specificity: Only equipment within the specific room is displayed.
• Occupant Rules: Permissions can be managed via EWEB.

Beacon Technology: The system utilizes beacon broadcasts to send messages to nearby devices. Mobile devices display location-based messages. Beacons are proximity-based, with the closest room listed first. Multiple hubs can be bound to a single room, ideal for open office environments.

Diagram Description: Two smartphone interfaces are shown, one displaying a list of devices and activities, the other showing Bluetooth pairing options. Another image depicts a conference room with two O3 Sensor Hubs labeled 'Hub 1 Room 1' and 'Hub 2 Room 1', illustrating proximity indicators ('Near' and 'Far').

Activity-Based Control

The O3 Sensor Hub facilitates activity-based control, allowing users to:

• Execute one-touch controls for light level, blind position, and temperature setpoint.
• Program custom activities tailored to specific needs.
• Re-use programmed activities across multiple rooms by storing them in EWEB.

Mobile App Interface: The app displays current room activity (e.g., 'MEETING') with temperature and CO2 levels, and lists other available activities like 'Yoga', 'Presentation', and 'Desk Work'.
