What batteries to use ???
The sensor consumes a hefty 10 Vdc at 6mA. The processor on the other hand only consumes a max of 3 mA @ 5 Vdc. I need at least 10 volts.
That means about .08 watts consumption @ 10Vdc +2 -0. Can any of you battery gurus out there tell me what type of battery would be good for this application??
