It integrates a 24-bit HX710B ADC with a piezoresistive sensor, delivering accurate 0-40KPa readings over a 2-wire serial interface. Compatible with 3.3V and 5V microcontrollers, it's a dependable choice for embedded monitoring projects.\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\u003eChip\u003c\/td\u003e\n\u003ctd\u003eHX710B\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMeasurement Range\u003c\/td\u003e\n\u003ctd\u003e0-40 KPa\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V-5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Interface\u003c\/td\u003e\n\u003ctd\u003e2-wire serial (CLK, DAT)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e24-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.1% FS\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\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003eDIY digital weather station with barometric pressure logging\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/drone-altimeter-kit-v2-build-a-lora-enabled-altitude-sensor-for-drones\"\u003eRC drone altimeter for altitude hold and terrain following\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eVacuum leak detector for automotive or HVAC diagnostics\u003c\/li\u003e\n  \u003cli\u003eSmart inflation system with pressure feedback for soft robotics\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis module works with any 3.3V or 5V microcontroller that supports a GPIO-based serial interface, including Arduino Uno, Nano, Mega, ESP8266, ESP32, and Raspberry Pi Pico. Use the HX710B Arduino library by Olav Kallhovd for hassle-free integration; connect CLK and DAT to any two digital pins and power the board with a stable supply.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 3.3V or 5V (matching your MCU logic level), GND to ground, CLK to a clock-capable digital pin, and DAT to a data pin. No external pull-ups are required, but avoid long wire runs to minimize noise—keep connections under 20 cm if possible.\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 all Arduino boards using the HX710B Arduino library. Just wire CLK and DAT to any digital I\/O pins and include the library in your sketch.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes it include tubing or connectors?\u003c\/summary\u003e\u003cp\u003eThe module ships as shown—no tubing or barbed connectors are included. You can solder a small nozzle from your own stock for direct pressure port attachment.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the accuracy and drift?\u003c\/summary\u003e\u003cp\u003eTypical accuracy is ±0.1% of full scale; long-term drift is negligible for most hobbyist applications. For critical measurements, allow a 10-minute warm-up and avoid rapid temperature changes.\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.
