Qwiic Scale - NAU7802 module for tensometric beam - SparkFun SEN-15242

Index: SPF-14405 EAN: 5904422352400

The module is based on a NAU7802 system enabling the reading of data from a strain-gauge beams. By connecting the model to the microcontroller, you can read the change in resistance of the beam with a small calibration, it is possible to make accurate measurements of weight. The board was equipped with clamp connectors and Qwiic connectors. It communicates using the I2C interface.

Description of product: SparkFun Qwiic Scale module NAU7802

The module is based on aNAU7802system enabling the reading of data from a strain-gauge beams. By connecting the model to the microcontroller, you can read the change in resistance of the beam with a small calibration, it is possible to makeaccurate measurements of weight. The board was equipped withclamp connectorsand Qwiic connectors. It communicates using theI2Cinterface. It works with a voltage of3.3 V.

When connecting the strain-gauge beam, the module is able to transfer the signal to one that can be read from the microcontroller you are using. NAU7802 is the ADCconverter with I2C output for amplifying and converting signals from the standard strain-gauge beam.

Pins from the module SparkFun NAU7802

The module communicates via the I2C interface. In addition, the module has the Qwiic connector which allows you to directly connect it tothe Qwiic shields.
