The Potentiometer is an input device that varies its resistance when the knob is rotated. It is commonly used for adjusting voltage levels, controlling brightness, or tuning input values in electronic circuits. The Gorillacell ESP32 Development Kit includes one Potentiometer module. It features mechanical stoppers at its minimum and maximum positions to prevent over-rotation and ensure durability during use.
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 Rotary Encoder detects rotational movement and its direction using two out-of-phase signals. Some rotary encoders also include an integrated push button switch, which is ideal for navigating menu-driven user interfaces or other interactive projects.
The Temperature and Humidity Sensor provides accurate measurements of the surrounding temperature and humidity.
