What is it?

This design is an isolated pH probe interface over I2C. Although it is designed for reef-pi, this board can be used with anything that can communicate over I2C (including Arduino).

What makes it special?

Unlike other pH probe boards, this product integrates voltage and signal isolation to ensure reliable, consistent pH readings.

The address is configurable based on the 2 jumper caps.

A1	A0	Address
Off	Off	0x45
Off	On	0x44
On	Off	0x43
On	On	0x42

Pseudocode for reading probe value

The address 0x45 with both jumper caps attached.

write 0x45,0x06 //SW reset write 0x45,0x40,0x06; //set config register for continuous conversion, 90SPS write 0x45,0x08; // start conversion

-loop to read value periodically: write 0x45,0x10 then read two bytes

Works great!

No problems installing and using with reef-pi and Leviathan board. Would love to be able to use an ORP sensor with this. Hope that will be a future option. Fast shipping. Also would be cool to have the nut that threads on included.

The new & improved board is excellent!

I've had both the old & new versions & I'm really impressed with the newest iteration. The board is sleek, added on noise filtering, & clearer labeling. This is definitely the best pH interface I know of!

Excellent Product

As the title says, excellent product. Easy to interface, easy to use! Even works with my cheap chinese probe I paid 10 bucks for on Ali Express!

Awesome little board :-)

This is the most affordable ph circuit board with galvanic isolation. Michale assembled it perfect. Pre wired connectors saved a lot of time. Thank you.
