  • Description

Introduction

The photoresistance sensor is consists of a photoresistance, a variable resistance and a LM393. This module has four pins, two pins are used to connect the power and ground, the others are digital output and analog output.


Technical data

Working voltage: 3.3 to 5V

Analog output and digital output

Adjustable sensitivity

Provided with a fixed bolt hole, convenient to install


Usage

When module is not up to the threshold in the condition without light or light intensity, the output port DO high level, when the external environment light intensity exceeds a set threshold, the module D0 output low level

Small digital output D0 with the microcontroller is connected directly, through the microcontroller to detect low level, thereby to detect environmental intensity change

Small digital output DO can directly drive the relay module, which can be composed of a photoelectric switch

Small analog output AO and our AD module, through the AD conversion, it can obtain more accurate numerical value of environmental light intensity
