Works at 5V logic level; for 3.3V boards, use a voltage divider or ensure ADC tolerance.\u003c\/p\u003e\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect the BNC probe interface to the module, then wire VCC to 5V, GND to GND, and analog out (Po) to an ADC pin. For accurate readings, calibrate with buffer solutions (pH 4.01 and 6.86) before first use. The output voltage is typically mV per pH unit, requiring software conversion.\u003c\/p\u003e\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\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, connect the sensor's analog output to any analog pin (A0-A5) and power with 5V. Use the Arduino's ADC to read pH values after calibration.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow often does the electrode need replacement?\u003c\/summary\u003e\u003cp\u003eThe glass electrode typically lasts 1-2 years with proper care. Store in storage solution (3M KCl) when not in use to extend life.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use this for continuous water monitoring?\u003c\/summary\u003e\u003cp\u003eYes, it is designed for continuous immersion. Ensure the probe tip stays wet and avoid drying; intermittent cleaning with pH calibration solutions maintains accuracy.\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.
