Texas Instruments unveiled a solar energy harvesting (SEH) development kit that converts ambient light into power for industrial, transportation, agricultural and commercial applications, including wireless sensor network systems. 
The credit card-sized eZ430-RF2500-SEH kit combines Cymbet’s EnerChip thin-film battery technology with TI’s MSP430 microcontrollers (MCU), CC2500 radio frequency (RF) transceivers and the eZ430-RF2500 development tool.
TI said the solution could be used to build self powered solar-based wireless sensor networks, eliminating system batteries, which cost time and money to periodically replace, especially in remote locations. Sampling is underway.
