Designed to operate indoors, the device requires only 200 lux to generate energy (typical lighting values in a building range from 200 lux in hallways, 500 lux on desktops and up to 1200 lux in display cases). The unit is comprised of a solar cell energy source, an energy reservoir, analog and digital sensor connections, a microprocessor for sensor control, and, a radio transmitter in a 0.8 x 1.6 x 0.4 in. footprint. The module stores sufficient energy to operate continuously for up to five days in complete darkness. With 50 µWs, a standard EnOcean transmitter will send an RF signal 300 ms outdoors, 30 m indoors through walls. The signal duration is approximately 1/1000 s. Units offer 3 analog and 4 digital inputs. The proprietary radio technology is approved for use in Europe (ETSI), US (FCC) and Canada (IC).
