A quick little project as a spin-off of a larger common shared design for an aquarium controller, I’ve knocked together a small inlet sensor and 12V driver with 4 channels, allowing you to hookup a float switch or attach a DC pump across all four channels. Programming is handled by USB, or a CAN bus attachment.
It shares a common CPU design and firmware build with my upcoming Reef-Pi controller and power bar, just dramatically simplified and providing a simple, safe DC output option.
It fits in a small 1455 series Hammond aluminum extrusion, a mere 55mm wide.
