1 x HX711 module.

User manual:
When measuring, external force is applied correctly to the outside. The expansion bar 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 have a shear force in the opposite direction, i.e. in the middle of the expansion bar must be able to experience bending changes under load, and on the other side of the expansion bar should be no obstacle.

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 is 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.
