Dual Analog Channels: Features two analog input channels with an integrated programmable 128x gain amplifier for versatile signal conditioning across various applications. Flexible Bridge Configuration: Input circuit can be configured for bridge sensors, supporting multiple sensor modes such as pressure and weighing, ensuring adaptability in different setups. Product Description: This module integrates a 24-bit high-accuracy A/D converter chip HX711, specifically designed for high-precision electronic scale applications. It includes two analog channel inputs with a programmable 128x gain amplifier. The input circuit supports bridge sensor configuration, enabling use in pressure and weighing sensor applications, making it a cost-effective, high-accuracy front-end solution. The strain sensor is compact, sensitive, and accurate. The sensor incorporates a half-bridge strain gauge with three operational modes. Specifications: Sensor Size: 34 x 34 mm (1.34 x 1.34 in) Sensor Internal Construction: 1000 ohm half-bridge strain gauge Measuring Range Options: 50 kg, 100 kg, 200 kg Package Includes: 4 x Weighing Sensors 1 x HX711 Module User Guide: During measurement, apply external force correctly to the outer side of the sensor. The strain beam section of the E-shaped sensor (the beam arm with white rubber located at the center of the strain gauge) and the outer side should generate opposing shear forces. This ensures the central part of the strain beam experiences bending deformation under load. Ensure no obstruction interferes with the strain beam’s movement on the opposite side. The sensor contains a half-bridge strain gauge setup, configurable for multiple usage modes.
