about solar products. I need to design with my group a device that reads
a gas gauge and sends a signal wirelessly to a computer. The voltage can
be about 4V and the watts we need is a quarter watt. The device must be
battery powered and the battery must be able to be used for a year. What
we have thought about doing is using a lithium ion rechargable battery and
use solar cells as a trickle charge. However every thing i have seen has
been for outside light. We are curious if these systems will work inside
like a solar calculator.
