Meanwhile you can choose also for higher Amp also e.g. 20 Amp for switching Aircon or so. The coil of this relais must by 12 Volt DC of coarse. SECOND: You can also use a 5 V - 6 V coil, but then you supply the temp module with a 6 Volt DC supply. (The MCU works on 5 Volt!) Works perfect! See More

Hello, Me, I used power first ring and duct tape "Duck Gorilla" Here are the steps: # 1: I drilled a hole on the start of the 2 power lines. # 2: I inserted a power first ring at the end of the copper line. # 3: I put an eyelet in the hole of the film and passing through the power first ring, then I crimped the eyelet. # 4: I soldered one of the electrical wires to the terminal. # 5: I put thick adhesive tape above and below the eyelet. Do the same on the other side of the film. It's easy to do, fast and secure!! See More
