Feature

●This module uses a highly accurate 24-bit A/D converter chip HX711, designed for high-precision electronic scales.
●The input circuit can be configured as a bridge sensor, the bridge pressure sensor modes (e.g. pressure, weighing), making it an ideal, high-precision, cost-effective front-end module for scanning.
●Two analogue channel inputs with integrated programmable amplifier with 128x gain.
●The weighing sensor is accurate and sensitive with a small volume.
●The sensor is a set of half bridge strain gauges with three modes of use.

Package list:
4 x weighing sensors.
1 x HX711 module.

User manual:
When measuring, external force is applied correctly to the outside. The expansion beam part of the E-shaped sensor (i.e. the beam arm with the white rubber in the middle of the strain gauge) and the outside should form a shear force in the opposite direction, i.e. in the middle, the expansion beam must suffer bending changes under load, and no obstacle must be present on the other side of the expansion bar.

Inside the sensor there is a set of half bridge strain gauges that can be used in the following three ways:
1. Use an external resistance sensor to form a full bridge measurement. The range corresponds to the range of a sensor: 50 kg. Requires higher external resistance requirements.
2. Use two sensors to form a full bridge measurement. The range is the sum of the ranges of the two sensors: 50 kg x 2 = 100 kg.
3. When using four sensors to form a full bridge measurement, the range is the sum of the ranges of four sensors: 50 kg x 4 = 200 kg.
