Arduino thermostat

 

Here is an "easy to make" Thermostat.
The goal was to replace an existing non working thermostat on a heat accumulation panel. Instead of buying a new one I decided to make my own.

The goal was to use basic electronic parts, to be cheap, fun to make and of course safe.
It is mainly based on a :

  • arduino (boarduino version) - board for the controler

  • TIL311 led digits - temperature visualisation (very expensive if you do not have some),

  • 5V stabilized power supply (NDS lite power bloc) 

  • DS18B20 - 1-wire temperature sensor.

  • BT12-600 triac - power switching (2000W load).

There is no PCB. It is up to you to make your own or use a prototype board like me.



Note

The package is not available as I have lost the Arduino source code...
