Only when the transmitter board output 0V can it prints pH 15.45 on the serial monitor.
Please check whether the transmitter board gets the suitable supply voltage range, that is, 3.3~5V.
Then short circuit the BNC input pin, the pH value on the serial monitor should be about 7.0. If not, please contact [email protected] for further help.
