Description

The 5±0.2V AC/DC pH Electrode Probe BNC with pH 0-14 Value Detect Sensor Module is a reliable solution for measuring pH levels across a wide range of applications, from hydroponics and aquariums to laboratory experiments. This kit includes a compact sensor module and a BNC-connected pH electrode probe, designed for seamless integration with Arduino, Raspberry Pi, or other microcontrollers. The sensor module operates on a heating voltage of 5±0.2V (AC/DC) with a working current of 5-10mA, consuming ≤0.5W of power. It detects pH values from 0 to 14 with a response time of ≤5 seconds and a settling time of ≤60 seconds, covering a temperature range of 0-80°C. The module’s analog voltage output is ideal for real-time monitoring, and its 42x32x20mm size with 4 M3 mounting holes ensures easy installation.The BNC electrode probe features a single-cylinder design for direct connection to compatible pH meters or controllers, offering a pH range of 0-14 and a temperature range of 0-60°C (or up to 80°C depending on the probe). It provides a zero-point accuracy of 7±0.25pH, an alkali error of ≤15mV, and a theoretical percentage slope of ≥98%, with an internal resistance of ≤250MΩ and a response time of ≤1 minute. The module operates effectively from -10°C to 50°C (nominal 20°C) and handles up to 95% RH (nominal 65% RH), making it versatile for diverse environments. For Arduino use, connect VCC and GND to a 5V supply, A0 to an analog pin (e.g., A0), and the BNC probe to the module’s input. Calibration with standard buffer solutions (e.g., pH 4.0, 7.0) is required, using the onboard offset potentiometer (near the BNC) by shorting the connector and adjusting to ~2.5V at pH 7. This kit is ideal for water quality monitoring, aquaponics, and educational projects, complementing your stepper motor setups with environmental sensing. Note: Avoid prolonged continuous use to extend probe life, and store the probe moist to maintain accuracy
