DIY MORE PH-4502C pH measuring module

Product detailed description

The pH measurement module allows you to measure the pH level in various liquids. With the E201, the probe can measure pH in the range 0 to 14 with an accuracy of ±0.5, while the measuring temperature range is 0 to 60°C.

V+ = +5V
G = GND
Po = analogue output for pH measurement
Do = digital alarm output - the setting of the switching value is done by a trimmer closer to the connection pins
To = analog output of thermistor for ambient temperature measurement

Calibration procedure for connection to boards Arduino - output range 0-5V:

1. Disconnect the probe from the BNC connector and short-circuit the BNC connector with a piece of wire (connect the center pin of the connector to the outer shell of the connector)
2. Measure the voltage at pin Po with a multimeter
3. With the trimmer that is closer to the BNC connector, set the Po output voltage to 2.5V. The trimmer is multi-turn, approx. 25 rpm.

You can then connect the probe and try to fine-tune it with the calibration solution.
