Illumra has introduced a solar-powered wireless door and window sensor. The battery-free sensor communicates using the EnOcean protocol to a variety of compatible actuator and controller products such as thermostats, relays, and room controllers, in addition to BACnet and Ethernet gateways for integration with energy-management systems. The sensor also includes onboard energy storage so it can operate in darkness for up to six days. It takes about a day to achieve a full charge.; 801.349.1200.
