The Redwood Sensor collects data on light levels, temperature and motion, transmitting this environmental data back to the Redwood Engines for dimming and controlling a connected Redwood Ready™ third-party LED fixture. The Sensor receives power from the Engine via category cable.
The Sensor contains a set of environmental sensors to improve platform efficiency, including:
- Tailored occupancy that accurately detects the presence or absence of people.
- Daylight harvesting, which enables each light fixture to respond automatically to changing ambient light levels throughout the day, and save energy.
- The collection and recording of the fixture’s operating conditions and fixture-specific identifying information.
The Sensor is easily installed in the ceiling tile or junction box near the fixture and accepts standard category 5e, 6 or 6a cable via RJ45 jacks for connections to the fixture and back to the engine.
The Sensor’s functionality can be divided into two units, the Redwood Sensor Pod and the Redwood Gateway for implementations that require special LED fixtures, traditional light fixtures, or non-ceiling installation.
The Sensor Pod contains the environmental sensors for determining the operating conditions of the fixture.
The Gateway profiles the lighting fixture in a commercial property and transmits light level, temperature and motion data from the Sensor Pod to the Redwood Engine via low-voltage category cable. The Gateway comes in two basic configurations, an LED Gateway which controls, powers and dims Redwood Ready™ third-party LED fixtures, or a Universal Gateway, which turns on and off any light fixture type (e.g. fluorescent, CFL, HID, LED, etc.) but does not provide power.
The Redwood Universal Gateway – Outage Relay can be used with a dry contact relay to communicate the system status of an Engine. The Outage Relay can be used in emergency lighting applications to switch on the power from a back-up system during a normal power loss or engine failure.
Both the Gateway and Sensor Pod are installed on or next to each light fixture and accept standard category 5e, 6 or 6a cable via RJ45 connectors or 18AWG via pre-terminated springs.
