Keyestudio EASY plug Photoresistor Sensor Module for Arduino STEAM

A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The principal is very simple. The resistance of photoresistor varies with incident light intensity. If the incident light intensity is high, the resistance decreases; if the light intensity is low, the resistance increases.
keyestudio EASY Plug photocell sensor is a semiconductor, integrated with a photoresistor, easy to use and very convenient for wiring.
It has features of high sensitivity, quick response, spectral characteristic and R-value consistence.
It can be applied in light-sensitive detector circuits, intelligent switch design and light- and dark-activated switching circuits.
This module should be used together with EASY plug control board.
