Product Description

The Adafruit NAU7802 contains a super-high-resolution 24-Bit differential ADC with extra gain and calibration circuitry that makes it perfect for measuring strain gauges / load cells or other sensors that have four wires that are connected in a Wheatstone bridge arrangement.

Each breakout comes with a NAU7802 ADC chip, plus some support circuitry, and 4 terminal blocks that can be used to connect a 4-wire sensor.

The E- pad connects to ground (often a black wire), the E+ pad connects to a generated voltage from the NAU7802 that can be configured from 2.4V to 4.0V for a solid positive reference (often a red wire).

Then A- and A+ pads connect to the differential outputs from the bridge. For example, connecting to a strain gauge these tend to be the white and green wires.

As the sensor is twisted and bent, the slight changes in resistance are converted to minuscule voltage changes that can be read by the NAU ADC for converting into force or mass measurements. You can use our Arduino library or CedarGrove's CircuitPython/Python library to configure and read the ADC for fast interfacing. Note that this sensor has a fixed I2C address, if multiple sensors are desired on one I2C bus, a multiplexer can be used.
