Safety Relay
Part of a bigger project called "Mushroom drier". A relay module made to temporarry interrupt the mains voltage, in case there is a failure with the control system( Arduino ) and the temperature exceeds the operating limits. The PCB looks splendid, a real bang for the buck. Tip: I ordered 5, but later I realised that I could've gotten 10 for the same money. That's insane, altough I don't need more than one board.
