Arduino Aquaponics: EnvDAQ with Water Temperature Sensor

The Environment DAQ is an open source Arduino shield used to track air temperature, relative humidity and light in aquaponic and hydroponic grow beds. An equally important parameter to track is root temperature and with the new prototyping area on the v2 Environment DAQ boards, it is easy to add a new sensor.
