Wireless sensor network terminal with thin PV module

EH-Terminal_0.png

EH-Terminal is a wireless sensor terminal to monitor environmental data such as temperature, humidity and light level without the need to change batteries by adopting a solar cell optimized for room light and secondary battery. The sensor network systems for indoor applications had a barrier in wide adoption by the issues of battery life, maintenance cost and the limitation of placement locations. This EH-Terminal overcomes those issues by using Ricoh’s high-efficiency thin die-sensitized solar cell and Hitachi Maxell’s ultra-thin laminated battery, and enables long and reliable wireless communication in a very small package. The EH-Terminal uses Dust Networks for communication with core network to attain high reliability and low power, and BLE (Bluetooth Low Energy) for communication with wearable terminals.
