Water temperature

Temp 2 - water temperature sensor

Measures temperature of fluids/liquids. This is a waterproof sensor to measure the temperature of watering fluid or nutrient solution (in case of hydroponic setup) and its suitable for aquaponics. It's also possible to use the sensor for standard measuring of outside air temperature. 

Based on measured values and settings You can drive pump or solenoid valve to fill with cold water when water in reservoir or aquaponic fishhold gets too hot for example. Or turn on water heating if it's opposite situation.

Resolution of 0,1°C.

For most effective measurement place the sensor approximately in half of the the reservoir tank. If used in aquaponics, ideal position is in the stream/runoff pipe.


As well as all other sensors, theese are connected to main unit using flat four-wire telephone cable with RJ-11 connectors. Tested cable length is 5,5m, standard supply is 5,5m.
