I have built, coded and tested an Arduino with DHT11 Temp & humidity Sensor and Relay
This will switch on the relay when Temp goes below 17 and turn off when Temp is above 22
I am happy with my build and ready to implement.
I only have one question - Powering the Arduino with Mains AC (In "Series" with the Heater if you will)
I don't want to have two power Supply's and I also don't want to Die. Taking a cautious approach
Some advice from more seasoned users would be much appreciated.
Can I use a USB 2 Pin Adapter (Iphone Charger) to Power the Arduino in this setup?
