Features High-Precision A/D Conversion: Features a 24-bit A/D converter for exceptional accuracy, ideal for building reliable electronic scales and measurement systems. Dual Analog Channels: Equipped with two analog channel inputs and a programmable 128x gain amplifier, enabling versatile measurements for various applications. Flexible Bridge Configuration: Configurable input circuit for bridge sensors allows multiple pressure and weighing sensor modes, ensuring adaptability in diverse setups. This module uses a 24-bit high-accuracy A/D converter chip HX711, designed for high-accuracy electronic scales. Two analog channel inputs with integrated 128x gain programmable amplifier. The input circuit can be configured as a bridge sensor, providing bridge pressure (e.g., pressure, weighing) sensor modes, making it an ideal high-accuracy, low-cost sampling front-end module. The weighting sensor is accurate and sensitive with a compact design. The sensor is a set of half-bridge strain gauges with three operational modes. Specification: Sensor Size: 34 x 34mm Sensor Inner Construction: 1000ohm half-bridge strain gauge Measuring Range: 50kg / 100kg / 200kg Package List: 4 x Weighting Sensor 1 x HX711 Module User Manual: During measurement, apply external force correctly to the outer side. The strain beam part of the E-shaped sensor (the beam arm with white rubber in the middle of the strain gauge) and the outer side should form a shearing force in opposite directions. The center of the strain beam must be able to undergo bending deformation under stress, and there should be no obstruction on the opposite side of the strain beam. Inside the sensor is a set of half-bridge strain gauges, which can be used in multiple configurations.
