Functional Housing for Dollatech AC sensor

My First Thing.

DollaTek AC 220V Microcontroller TTL Level Optocoupler Isolation Module from Amazon. Used to sense a voltage applied to a ac line and transllate to a ttl digital in. Usefull for my Underfloor heating thermostat tester. Comes as a bare circuit, with live wires exposed. This Thing is to stop you putting fingies where they shouldent be.

Made for myself as a functional print. Thought I would share with you.

Legally This is for "entertainment only". Always be safe with Live Electricity.

Search on Amazon for the device. I think there are a few slight varients. I made it for this version.
