ILLUMRA Door/Window Sensor Saves Energy

ILLUMRA, the leader in wireless battery-free controls, announced the release of a new solar powered wireless Door/Window Sensor. This new product maximizes the energy savings of heating and air conditioning systems by providing wireless status of windows and/or doors. The breakthrough technology may be seen at the GreenBuild Show in Chicago, Illinois (EnOcean/ILLUMRA booth #583).

Door/Window SensorEnergy waste can be reduced by 20 to 60 percent by disabling blowers and/or adjusting temperature setpoints in HVAC systems when windows and doors are left open. The wireless Door/Window Sensor is a key component to reducing energy waste in hotel, condominium and dormitory buildings.

“We are excited to help building operators reduce energy waste through the use of the easy to install, tamper resistant, maintenance free window/door sensors,” said Jan Finlinson, Director at ILLUMRA. “Energy management professionals can leverage this product to reduce operating costs and the environmental impact of the buildings for which they are responsible.”

The wireless battery-free sensor communicates using the EnOcean protocol to a variety of compatible actuator and controller products: thermostats, relays, room controllers; as well as BACnet and Ethernet gateways for integration with energy management systems. The sensor also includes on board energy storage that can operate the device in darkness for several days.

The ILLUMRA light sensor is small, measuring only 3.86 x .62 x .81 inches (98.04 x 15.75 x 20.57 mm) and attaches easily to doors and windows (peel and stick). The ILLUMRA light sensor is made of recyclable plastic, is RoHS compliant, qualifies for LEED credits and helps buildings comply with International Green Construction Code standard 189.1.

ILLUMRA is the largest North American supplier of self-powered, battery-free, wireless lighting control and energy management systems, and a member of the EnOcean Alliance. ILLUMRA products operate using the EnOcean protocol: the standard for low-power wireless communication. Transmitters harvest the energy they require from the motion of a switch, light on a solar cell, or from temperature differentials. This allows them to operate indefinitely without the use of batteries. Products are sold via dealers and OEM partners throughout the world.
