Switching 220VAC

I'm going to use a S202T01 to switch the 220V. They are easy to get, you can load them with 2A and where made for this job. The 220 Ohm resistor is tested and works OK with a Arduino. For Pompie the circuit has to be double for the air- and waterpump.

The S202T01 consists out of two triacs and a led to switch them on and off. The AC and DC parts are completely separated and to be safe a used screw-connectors to wire them to 220V.

Next: water level sensor
