Gorillacell Module 030: Weight Sensor
Table of Contents
The Weight Sensor measures the weight of an object. It consists of a weighing platform containing a load cell, which changes its electrical resistance when a force is applied, and the platform itself.
The sensor is paired with a driver board that uses the HX711 24-bit Analog-to-Digital Converter (ADC). The HX711 amplifies and converts the analog signal from the load cell into a digital signal that can be processed by a microcontroller. The module communicates with the microcontroller via a Serial I²C protocol, making it easy to interface with devices like the ESP32.
The Gorillacell ESP32 Development Kit includes one Weight Sensor module, consisting of both the weighing platform and the driver board, ready for experimentation and weight measurement projects.
