Hi all,
we have a problem regarding the long term calibration of our modbus pH sensors.
For the calibration modbus commands in hex must be sent which is not user-friendly for end-customers.
Is there any other / easier way to calibrate the sensors (any kind of user interface)?
Thank you and kind regards
Maren
Hi there,
I would spin up an MIT ai3 (app inventor 3) make one , it’s perfect for this tiny code requirement.
and if you add in some BLE you could do all of it from the mobile app.

you just need to write the code, so the user can enter the ph 7.0 and the code will push the aproprpriate value to the sensor
It was great
check the experiment once again
