Using for temperature logging & light


 

   The Logger has been tested with the sensors below and can be used with up to 7 sensors, the use's have been mainly

   for solar heating systems.

   Log of hot water take over 24 hours, notice the bath takes all tank!!, also light in the room + temp

   tank temperature was using a LM335 temperature sensor.

  

 

 

  

    4 days log of sunlight & temperature
