Sparky's Widget - New devices for pH reading

[Carlos Neves]

Hi,

I found the Sparky's Widget blog. There we can see some purposes for pH monitoring. One of them is the LeoPhi standalone pHmeter. They are different purposes that the pHduino. Take a look at Projects.

The LeoPhi is a board (not shield) with a microcontroller and the analog circuit.
