I have bought this Analog Ph Sensor today, and one of the cautions the designer has left was:
"After completing the measurement, disconnect the pH probe from the signal conversion board. The pH probe should not be connected to the signal conversion board without the power supply for a long time."
So does this literally mean I must physically disconnect the probe, or will it be ok to have a timer circuit that flicks a switch to off that I would program based on the sensor's response time?
Unfortunately I'm sorry if this is an obvious one to many, I really haven't taken proper consideration of electronics before.
