PH Sensor Kit

This pH Sensor is a scientific instrument used to measure the hydrogen ion activity in water-based solutions. The sensor kit comes with a pH probe and sensor board, the latter of which is used for signal conditioning the pH probe output to between 0-5V. The pH probe is capable of detecting pH levels between 1 to 14. A typical pH sensor consists of two electrodes called glass electrode and a reference electrode.

How to calibrate the pH sensor?

The pH sensor can be calibrated by shorting the Vin and GND terminals at the probe side, thereby emulating a signal of pH 7. The onboard potentiometer near the BMC probe connector can then be adjusted to give an output of 2.5V between the Po and GND pin. Alternatively, you can also use analogRead() on the Arduino to calibrate it to 2.5V. For detailed instructions, please check out our pH sensor blog linked below.

Few guidelines to use the sensor properly

  • Make sure the sensor is properly calibrated.
  • Make sure the probe is dipped in deionised distilled water after each reading for at least a minute.
  • Make sure the sensor is given at least a few minutes to settle down in it's reading after dipping it in a solution.

Here is the link to the PH Sensor Blog for a detailed explanation.

PH Probe Sensor Pinout

  • TO – Temperature output
  • DO – 3.3V Output (from ph limit pot)
  • PO – PH analog output ==> Arduino A0
  • Gnd – Gnd for PH probe (can come from Arduino GND pin) ==> Arduino GND
  • Gnd – Gnd for the board (can also come from Arduino GND pin) ==> Arduino GND
  • VCC – 5V DC (can come from Arduino 5V pin) ==> Arduino 5V pin
  • POT 1 – Analog reading offset (Nearest to BNC connector)
  • POT 2 – PH limit setting

Package Includes:

  • pH Probe
  • pH sensor board
