Description

The analog pH sensor kit is designed for precise measurement of hydrogen ion concentration in aqueous solutions. It employs a laboratory-grade glass electrode probe connected via a BNC interface to a signal conditioning module. The module provides power regulation and outputs a stable analog voltage signal proportional to the pH level, which can be read directly by the analog input of an Arduino, Raspberry Pi, or other microcontroller.

The system requires calibration using standard buffer solutions (pH 4.00, 7.00, 9.18) for optimal accuracy. The integrated potentiometer allows for gain adjustment to match the probe’s output to the specific measurement range. The probe is intended for intermittent use and should not be left immersed for extended periods to preserve the reference electrode.

Key Features

  • Industrial-grade pH electrode with BNC connector for reliable measurements
  • Compact signal conditioning module with power indicator LED
  • User-adjustable gain potentiometer for precise calibration
  • Simple analog voltage output for direct microcontroller ADC interfacing

Frequently Asked Questions

What is the power supply requirement for this pH sensor module?

The module requires a stable 5V DC power supply. For best accuracy, use an external switching power supply with a voltage as close as possible to +5.00V. The module includes a power indicator LED.

How do I calibrate the pH sensor for accurate readings?

Calibration requires standard pH buffer solutions (typically pH 4.00, 7.00, and 9.18). First, calibrate the offset using pH 7.00 buffer. Then, adjust the on-board gain potentiometer using pH 4.00 buffer. The probe must be rinsed with deionized water between different solutions.

Can I interface this sensor directly with a Raspberry Pi or ESP32?

Yes, but note the module outputs an analog voltage. You will need an external analog-to-digital converter (ADC) for the Raspberry Pi, as it lacks built-in analog inputs. The ESP32 has built-in ADCs and can read the signal directly from the module's PH2.0 interface.

What is the maximum immersion time for the pH probe?

This is a laboratory-grade probe and should not be immersed in liquid for extended periods. It is designed for intermittent measurement use. Prolonged immersion can degrade the reference electrode and affect measurement accuracy.
