Hi, I just started experimenting with the raspberry and found this project. Its amazing
So I decided to give it a try and managed to get a temp sensor working. After that i bought the ORP Probe from anyleaf and its module.
I thought it can be used to measure the PH ? Is this right ?
The next thing im a bit confused about is how to calibrate the Probe.
Is this the right solution :
or something like this :
Ive read all the datasheets from anyleaf and the instructions and googled some information on probes and calibration. But the more i read the more i get confused xD
Thanks for your help
