With the high demand for quality pH interfaces that can communicate over many different methods, we decided to update our very popular standard pH interface with the Atmega32u4 line of micro-controllers. This update makes an even more robust and powerful unit thats features user programmability and ease of use at levels never seen in units like this.
If you have ever wanted to log pH levels, run experiments or even automate a reef tank or garden this unit is made to help! The hardware is Arduino compatible making it extremely easy to reprogram, and also features some key pins broken out on headers!
We had a lot of users email us with projects and many had some sort of control programmed on top on normal pH readings, keeping this in mind we choose to incorporate the larger micro-controller! We hope to see some more cool projects so please email them and we'll feature them on the blog!
