Keyestudio EASY plug Photoresistor Sensor Module for Arduino STEAM

The Keyestudio EASY plug Photoresistor Sensor Module is an analog light-detection sensor designed for educational STEAM projects. It is ideal for students, educators, and hobbyists looking to build light-sensitive applications without complex wiring. This module is designed to be used in combination with an EASY plug control board.

Light-dependent resistance technology

This module features an integrated semiconductor photoresistor, also known as a light-dependent resistor or LDR. Its resistance decreases when exposed to high light intensity and increases in low light, providing a simple way to measure ambient brightness.

Hassle-free plug and play

Equipped with the EASY plug interface, this sensor allows for quick and secure connections to your compatible control board. This eliminates the need for loose jumper wires and breadboards, making it perfect for classroom environments.

High sensitivity and quick response

The sensor offers quick response times and consistent R-value performance for reliable light detection. Its high sensitivity makes it highly capable of detecting subtle changes in environmental lighting.

Practical automation applications

This module is highly suited for building intelligent switch designs, light-sensitive detector circuits, and light- or dark-activated switches. It provides a hands-on introduction to real-world automation concepts.

Designed for STEAM learning

By simplifying the hardware setup, this sensor allows students to focus on programming and logical thinking. It is an excellent resource for school science labs, coding clubs, and home makerspaces.

Analog output and 5V operation

The module operates at a standard 5V working voltage and outputs an analog signal based on the light intensity. Beginners can easily get started using the step-by-step Wiki page tutorial.
