Liquid pH 0-14 Value Detection Sensor Module with pH Electrode Probe (BNC) - pH Sensor Module

The Liquid pH 0–14 Value Detection Sensor Module with pH Electrode Probe is a complete pH measurement solution designed for accurate detection of acidity and alkalinity in liquid samples. Covering the full pH range of 0 to 14, this module is ideal for water quality monitoring, laboratory experiments, aquaculture, hydroponics, chemical processing, and DIY electronics projects.

The system consists of a high-impedance pH signal conditioning module and a standard BNC pH electrode probe, ensuring stable, accurate, and repeatable readings. It is fully compatible with popular microcontroller platforms such as AVR, Arduino, STM32, ESP32, and other embedded systems, making it suitable for both educational and industrial applications.

Features of Liquid pH Detection Sensor Module:

1. Measures full pH range from 0 to 14

2. High-accuracy pH electrode with BNC connector

3. Analog voltage output for easy microcontroller interfacing

4. High input impedance signal conditioning circuit

5. Adjustable gain and offset (via onboard potentiometer)

6. Stable and low-noise measurement performance

7. Easy integration with AVR, Arduino, STM32, ESP32 platforms

8. Suitable for long-term liquid monitoring applications

9. Ideal for water testing, hydroponics, aquariums, and labs
