Gorillacell Module 035: Light Sensor

The Light Sensor, also known as a Photoresistor or Light Dependent Resistor (LDR), is an electronic component that varies its resistance based on the amount of light intensity falling on it. When exposed to bright light, its resistance decreases, and when in darkness, its resistance increases. The Gorillacell ESP32 Development Kit includes one Light Sensor module for experimenting with light detection, automatic lighting control, and other photo-sensitive applications.

Gorillacell Module 030: Weight Sensor

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.

Gorillacell Module 026: Ultrasonic Sensor

The Ultrasonic Sensor measures distance using high-frequency sound waves. The Gorillacell ESP32 Development Kit includes an Ultrasonic Sensor module, driven by the HC-SR04 driver chip, which handles generating and receiving the sound waves. The sensor has two “eyes”: one acts as a transmitter that emits sound waves, and the other serves as a receiver that detects the waves reflected back from an object.
