24 Bits HX711 Chips: This arduino pressure sensor module uses a high-precision 24-bit HX711 A/D converter chip, designed for high-precision electronic scales. Fast and smooth response, accurate measurement data, virtually error-free. Amplification 128X: The HX711 module has two analog channel inputs with an integrated programmable amplifier with 128x gain. Multiple Uses: The input circuit can be configured as a bridge sensor, providing arduino bridge pressure sensor modes (e.g., pressure, weighing), making it an ideal high-precision, low-cost sampling front-end module. High Sensitivity: The Arduino force sensor features precision and sensitivity, as well as a small volume.

The strain 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 outer side should form a shear force in the opposite direction, that is, the middle of the strain beam must be able to undergo bending changes under tension, and there must be no obstacles on the other side of the strain beam. Inside the sensor is a set of half-bridge strain gauges, which can be used in the following three ways: 1. Use one sensor with an external resistor to form a full-bridge measurement. The range is the range of one 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: 50kgx2 = 100kg. 3. Use four sensors to form a full-bridge measurement, the range is the sum of the ranges of four sensors: 50kgx4 = 200kg Note: Please note that the new type and old type of this product will be sent randomly, and please make sure you don't mind before ordering.
