For connecting the measuring probe to the platform Arduino.
Part of delivery is not of the measuring probe. We recommend that you together with the probe https://arduino-shop.cz/arduino/1234-sonda-pro-mereni-ph-1458420891.html

 

 Power supply: 4V – 6V

Pins:

– The output of the temperature sensor for temperature compensation. At a temperature of 25°C is the voltage of about 3.6 V with increasing temperature the voltage decreases (with a delay). At 100°C is the voltage of about 0.85 In.

Do – digital output (5V / 0V) responsive to the set threshold value ph. The threshold is set by the potentiometer closer to the output pins.

After – the output of the ph sensor (-0.4 V to 0.4 V) amplified 2x. The mean value of the voltage of the ph sensor 0V (PH7) is shifted in the range of about 1V to 2.5 V using the potentiometer closer to the connector for the ph probe.

G – GND (ground)

G – GND (ground)
V+ - 5V
