reef-pi

Posted on Posted in Uncategorized

reef-pi is an open source aquarium automation system that runs on a raspberry pi. This build uses a custom designed hat that makes it super easy to build. It supports 16 outlets, 2 ph probes, 3 temperature sensors, 2 ATO sensors, and 2 lights with 3 channels each. I also made a 5 foot light bar to fix some dimness on the back wall. More details are on my reef2reef build thread.

It looks fine from the outside, but the inside is dang mess! It took so long to get everything tucked and jammed in.

PCA9685 and ULN2803 are integrated into the hat, along with a bunch of JST connectors which were supposed make everything neat. Ha! I also added reverse current blocking and the eeprom for official hat status.

I have some extras listed on Tindie.

The UPS needed modification in order to support individual outlet control. I pulled out the live strip and cut parts out of it. An 8 channel relay board now controls it.
