EZO Sensors - Integration and Calibration in NodeMCU
Posted: Wed Apr 21, 2021 11:28 pm
Hi friends.
First I want to thank all the members of the LEDgardener forum. Thanks to the information I found in the forum, I managed to integrate and calibrate the EZO-ph and EZO-ec sensors in Tasmota 9.2.
I recommend that the integration of the EZO-ph and EZO-ec sensors be carried out in a NodeMCU v.2 device, I had problems with the integration using the ESP32.
They should also use Tasmota 9.2
The commands used for calibration are:
--------
pH:
Sensor78 Cal, mid, 7.00
Sensor78 Cal, low, 4.00
Sensor78 Cal, high, 10.00
Reference:

---------
EC:
Sensor78 Cal, dry
Sensor78 Cal, low, 12880
Sensor78 Cal, high, 80000

-------------
I had the problem that when I calibrated one of the sensors the other was set to 0.00, so I recommend that the calibration be done separately from the other, that is, first connect only the EZO-pH sensor to the NodeMCU V.2 and calibrate, once calibrated disconnect it, then connect the EZO-ec and calibrate it, once calibrated both separately just connect the two sensors to work with them.
It is the way it turned out for me, I hope it helps you.
