When using the Heating and Air-conditioning system in the house, the control unit is located in the master bedroom, and controls the temperature there. When I work in the office, the temperature is not well maintained.
I need to have a remote temperature sensor in the office, controlling the Heating/AC system.
Here is the first experimental working prototype:
And Remote sensor:
Next I plan to replace the sensor with DHT22, improve the UI, and package the whole thing together in boxes.
The second power regulator on the first picture is now removed. I used it for quick test before I adjusted the voltage from the adjustable buck AC/DC regulator on the top.
I will post more pictures and the Visuino project when I get it all working to my satisfaction ;-) .
