Hi Dave. Thanks for the response.
Depending on the range that is needed, I suppose it could use Bluetooth.
What I am trying to get at is: I need to make a system that calculates force in an object when struck (Accelerometer), then sends that force back to a Computer/phone... and it has to power itself, so first, I need to figure out how much energy needs to be generated for each time the Force (1-3 digit number) is sent to the computer, for the system to function.
