Fixing measurement bug in soil moisture sensor #125

Closed mtlynch closed 7 years ago

mtlynch commented 7 years ago

The second reading was coming in wrong because we weren't turning off both GPIO pins before we slept, so there was probably some remnant charge on the first pin during the second read. Adding in a turn_pin_off call to ensure that both pins are off and have time for the charge to dissipate.
