This cool Atlas Scientific product allows you to measure pH and temperature (EZO pH, EZO temperature supplied) and can send the measurements to an MQTT server if needed.

The board has in total 3 EZO slots, so if you need for example EC (electro conductivity) in the future it has got you covered. 2 of the slots are electrically isolated.

The RPi pinheaders are stackable, allowing for more than 3 EZO boards.

The software is running on an industry standard RPi. You can update the Atlas software running on it any time.
