DFRobot - Gravity: I2C 1Kg Weight Sensor Kit - HX711 (Full Kit with Acrylic Base, Ready-to-use)

The weight sensor is a practical sensor close to daily life scenes. It can make many interesting applications by acquiring the weight information of objects, such as household electronic scales, daily necessities weighing, daily necessities remaining alarm，and Internet of Things weighing platforms.

Why choose this Weight Sensor Kit? Unlike the other weight sensor which requires complex coding and external structural parts, this I2C Kit includes a sturdy acrylic base and features a built-in calibration algorithm. Users can build a working scale in minutes without soldering or writing hard calibration codes.

This weight sensor kit is equipped with all the accessories needed to build the scale, which reduces the difficulty of structure construction so that anyone can quickly create an electronic scale to obtain the weight information of the object. In addition, because everyone has different installation methods and usage habits, the sensor needs to be calibrated. The traditional method is to use a separate calibration code to obtain the calibration value. To optimize this problem, the signal adapter board in this kit is built-in The calibration algorithm can calibrate the weight information with one key, and there is no need to run a separate code for calibration.
