{"title":"SparkFun OpenScale","handle":"sparkfun-openscale","url":"/products/sparkfun-openscale","description":"The SparkFun OpenScale is an open-source weight measurement board designed for load cells. Simply connect a four-wire or five-wire load cell of any capacity, plug into USB, open a serial terminal at 9,600 bps, and you'll immediately see mass readings. A built-in serial menu lets you configure calibration values, sample rate, timestamps, and units of precision.\n\nDesigned for static and continuous weighing applications — such as monitoring systems, conveyor belts, and long-term data logging — the OpenScale can operate unattended for months. An on-board TMP102 temperature sensor records ambient temperature alongside weight data.\n\nKey Features\n\n\nHX711 24-Bit ADC – High-resolution load cell amplifier for accurate weight measurement\n\nATmega328P Microcontroller – Handles serial communication and configuration\n\nTMP102 Temperature Sensor – Records ambient temperature alongside weight data\n\nFT231 USB-to-Serial – Mini-USB connection for data output\n\nConfigurable Baud Rate – 1,200 to 1,000,000 bps (default 9,600 bps 8-N-1)\n\nSerial Configuration Menu – Set calibration, sample rate, timestamps, and precision via terminal\n\nMulti-Cell Support – Works with single load cells or four sensors in Wheatstone bridge configuration\n\n\nIdeal For\n\nDIY weigh scales and measurement systems\nLong-term unattended weight monitoring\nIndustrial and conveyor belt weighing\nData logging with OpenLog or similar serial loggers\n\n\nPackage Contents\n\n1× SparkFun OpenScale Board\n\n\nResources\n\nOpenScale Applications &amp; Hookup Guide\n","vendor":"SparkFun","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":11898,"title":"Default Title","sku":"SF-SEN-13261","price":79.35,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
