Built a salinity and temp monitor/salinity controller for a class.

[Sinibotia]

Hey folks, I wanted to share this project I built for my Marine Engineering literacy class using arduino!(I'm finishing up a degree in oceanography). It's a salinity/temperature monitor, built using an Atlas Scientific conductivity probe and a DS18B20 waterproof temperature probe. It also hooks up to an outlet via a 5V relay. When the salinity gets above 33.5PSU(~1.025 specific gravity) the outlet turns on for a few seconds; the outlet is hooked up to a pump in a bucket of distilled water. It's not the most sophisticated build and I definitely have ideas for improvements but it's my first big DIY reefing project.

If anybody is interested in more details, wants the code, etc; I'm more than happy to share it all if there's interest!

I’d like to see your code

Cool project by the way

Ah a fellow programmer and DIY reefer. Nice build

I'm not the best programmer lol. I knew python, matlab, R and some java going into this class. C++/arduino has been an adventure. And this is my first experience playing with hardware too!

I am sure you have checked out Reef-pi right?

The salinity probe is a nice touch though! Thanks for sharing

Very cool!

Yeah, I have looked into it a bit! It's a lot like another project I'm working on, which is building an Open CTD (a lot like reef pi, but less about controlling and more about data collection, as an oceanographic tool).

hi, i was just thinking about building such a thing too, for my tank, to check the salinity, can you send me the project? Thanks in advance
