eZ430-RF2500-SEH Overview

1.1 Solar Energy Harvesting

The eZ430-RF2500-SEH is a complete Solar Energy Harvesting development kit to help create a

perpetually powered wireless sensor network based on the ultra-low-power MSP430 microcontroller.

The Solar Energy Harvesting module includes a high-efficiency solar (2.25 in x 2.25 in) panel optimized for

operating indoors under low-intensity florescent lights, which provides enough power to run a wireless

sensor application with no additional batteries. Inputs are also available for external energy harvesters

such as thermal, piezoelectric, or another solar panel.

The system also manages and stores additional energy in a pair of thin-film rechargeable EnerChips

which are capable of delivering enough power for 400+ transmissions. The EnerChips act as an energy

buffer that stores the energy while the application is sleeping and has light available to harvest. The

batteries are environmentally friendly and can be recharged thousands of times. They also have a very

low self discharge, which is vital for a no-power, energy harvesting system.

The eZ430-RF2500 is used to run the energy harvesting application. It is a complete USB-based MSP430

wireless development tool and provides all the hardware and software necessary to use the

MSP430F2274 microcontroller and CC2500 2.4-GHz wireless transceiver. It includes a USB debugging

interface that allows for real-time, in-system debugging and programming for the MSP430, and it is also

the interface to transfer data to a PC from the wireless system.

The integrated temperature and RF signal strength indicators can be used to monitor the environment,

and many external sensors can be used to collect additional data.
