SparkFun OpenScale IoT – An ESP32 board with HX711 ADC for smart scales with WiFi and Bluetooth connectivity

The SparkFun OpenScale – IoT project is a ready-to-use ESP32-based IoT smart scale with open-source hardware and firmware support that makes it easy to read precise weight data from load cells without writing custom code from scratch for basic operation. It handles amplification via the HX711 24-bit ADC, calibration, temperature compensation (using the onboard TMP102 and an optional external DS18B20 probe), and serial output/configuration through a simple text-based menu. It also features Wi-Fi for live data and OTA firmware updates, requiring no dedicated apps—just standard terminal tools and a browser for viewing data. Additionally, there is a Qwiic I²C connector for adding extra sensors or displays. The board operates from 5 V with a typical current consumption of 80 to 100 mA, supports selectable output data rates of 10 or 80 SPS, and includes an adjustable gain for accurate measurements in long-term monitoring setups.
