Description
Pressure sensor for Arduino works in the range of up to 1 kg. It is based on HX711, it has 24-bit analog-to-digital converter designed to scale weight and control applications for direct connection with the strain-gauge beam.
Connection
The converter's module has four screw connectors for connecting the strain-gauge beams. The supply voltage converter is from 2.6 V to 5.5 V. The Arduino module connection is easier because because of the applied Gravity connector.
Example of connecting to Arduino.
