This PH sensor Module consists of PH sensor also called as PH probe and a Signal Conditioning Board which gives an output which is proportional to the PH Value and can be interfaced directly to any Micro-controller.

The pH sensor components are usually combined into one device called a combination pH electrode. The measuring electrode is usually glass and quite fragile. Recent developments have replaced the glass with more durable solid-state sensors. The preamplifier is a signal-conditioning device. It takes the high-impedance pH electrode signal and changes it into a low impedance signal which the analyzer or transmitter can accept. The preamplifier also strengthens and stabilizes the signal, making it less susceptible to electrical noise.

pH and ORP probes are both used for measuring the acidic intensity of liquid solutions. A pH probe measures acidity on a scale from 0 to 14, with 0 being the most acidic and 14 being the most basic. Similarly, an Oxidation-Reduction Potential (ORP) probe returns a voltage proportional to the tendency of the solution to gain or lose electrons from other substances (which is linked directly to the pH a substance).

Pins of PH sensor Module

  • T1: 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.
  • 2V5: 
  • Po: 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 may use the potentiometer for the ph probe.
