Gorillacell Module 035: Light Sensor

Table of Contents

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.

BASIC INFORMATION

Device Category Interface Chipset Description
Input Sensor Cell Analog - -

PINOUT

It has 3 pins which are

  1. G - for the ground pin,
  2. V - for the supply voltage, and
  3. S - for determining the analog value of the Light Sensor module.
  4. An Analog to Digital Converter (ADC) peripheral will be used in order to determine the Light Sensor value.
