Energy Harvesting Applications

Silicon Labs enables to implement self-sustaining, ultra-low-power wireless sensor networks. In addition to being environmentally-friendly and virtually inexhaustible, harvested energy provides a cost-effective, convenient alternative to conventional batteries.
The appeal of completely self-powered circuits in today's socioeconomic climate is clear:
  • Lifetime operation
  • No batteries or maintenance
  • Environmentally-friendly design
  • Lower system costs

Energy Harvesting Reference Design

Silicon Labs' Energy Harvesting Reference Design (ENERGY-HARVEST-RD) consists of a wireless sensor node and a USB wireless adapter. The wireless sensor node is powered by a solar cell. There is an auxiliary input that will allow power to be sourced from other energy harvesting alternatives such as thermal, piezo or RF. The Si1xxx measures temperature (using an on-chip temperature sensor), light level and charge level. This sensor information is transmitted wirelessly to the USB wireless adapter. The sensor data is then presented on a GUI for a PC.
