This Arduino electronic weight sensor is capable of detecting a weight of 1kg. It is based on the HX711, a precise 24-bit analog-to-digital converter designed for weight scales and industrial control applications, which allows direct connection to a load cell sensor.

The Arduino electronic weight sensor reduces the cost of electronic scales while simultaneously improving performance and reliability. The connection of this sensor uses the DFRobot Gravity Interface. The output adopts compact terminals that facilitate the connection of the sensor. It is the best choice for electronics enthusiasts to build small home scales.
