It's designed for continuous monitoring in hydroponics, aquariums, pools, and laboratory experiments. With simple calibration and wide compatibility, it provides reliable pH readings from 0 to 14.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e0 - 14 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e0 - 5V (analog)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eProbe Type\u003c\/td\u003e\n\u003ctd\u003eGlass electrode, BNC connector\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e≤ 1 minute\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e0°C - 60°C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eHydroponics nutrient solution pH controller\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/aquarium-water-quality-monitor-kit-with-arduino-tds-and-temp\"\u003eAquarium water quality monitor and alert system\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eSwimming pool pH level automatic adjuster\u003c\/li\u003e\n  \u003cli\u003eSoil pH testing rig for agricultural projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks with any microcontroller or single-board computer that reads 0-5V analog signals, such as Arduino Uno, Mega, ESP32, or Raspberry Pi via an ADC. The module amplifies the mV-level probe signal to a 0-5V range, so no extra interfacing is needed. Use with a 5V supply and connect the analog output to an analog input pin.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V, GND to common ground, and the analog output to an ADC pin (e.g., A0 on Arduino). For best stability, use a dedicated 5V supply and avoid long unshielded wires. If readings drift, check the probe connection and recalibrate.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, the module outputs 0-5V analog, which can be read by any Arduino board using an analog input pin like A0. Just supply 5V and ground.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I calibrate the pH sensor?\u003c\/summary\u003e\u003cp\u003eUse buffer solutions of known pH (typically 4.0 and 7.0). Immerse the probe, adjust the onboard potentiometer until the output voltage matches the expected value for that pH, then repeat for the second point to set the slope.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the probe need special storage?\u003c\/summary\u003e\u003cp\u003eThe glass electrode should be kept wet in storage solution or pH 4 buffer when not in use. Never store it in distilled water as that leaches ions from the glass bulb.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
