This Arduino-based electronic weight sensor is capable of detecting a weight of up to 1kg. It uses a precision 24-bit analog-to-digital converter called HX711, which is designed for weight scale and industrial control applications, to interface directly with a bridge sensor.
This electronic Arduino weight sensor is not only cost-effective but also offers improved performance and reliability. It uses the DFRobot Gravity Interface for easy connection and has a compact terminal for output. It’s an excellent choice for electronic enthusiasts who want to create their small home scale.
