Use the HX711 breakout board’s E+\/E‑\/A+\/A‑ channels; keep wires twisted and away from switching noise sources for stable readings.\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, it works with any Arduino board when paired with an HX711 amplifier module. The amplified digital signal is read via a two‑wire interface (data and clock).\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDo I need an amplifier to use this load cell?\u003c\/summary\u003e\u003cp\u003eAbsolutely. The raw output is only a few millivolts, so an HX711 or similar instrumentation amplifier is required to boost the signal to a readable range for microcontrollers.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the maximum load before damage?\u003c\/summary\u003e\u003cp\u003eThe sensor’s safe overload limit is 150% of rated capacity (30 kg). Exceeding this may permanently deform the metal spring element and ruin 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.
