Hello all,

I'm pretty new to Arduino and still learning.

Instead of Atlas Scientific sensors, I have purchased the following:

- GRAVITY: ANALOG PH SENSOR / METER PRO KIT
- GRAVITY: ANALOG ELECTRICAL CONDUCTIVITY SENSOR

Is it possible to use these without the shield? Is it possible to use the Arduino Due instead of Mega? Would there be any benefit? Is there an alternative to the shield?

Any idea how to hook it together?

Thanks.

Short answer yes.

I have the Gravity PH Meter Pro connected directly to an ESP32 that runs Arduino Code which then sends the data to Home Assistant via MQTT.

My next project is moving it from Arduino to ESPHOME which seems like its not too difficult to do.

Yes, but don't.

I tried all the other cheaper routes before ending up with atlas in the end.

In short, everything else is trash, atlas is king and the next step up is 2k$ or so...

Just don't bother with Chinese probes and ec meters..

My two cents
