Introduction

Here comes DFRobot's new Analog Ambient Light Sensor. Brand new design and much more convenient to use.This module help you to detect the light density and reflect the analog voltage signal back to Arduino controller. You can set the threshold of voltage level to trig other unit on Arduino project.

Specification
• Supply Voltage 3.3V to 5V
• Illumination range 1 Lux to 6000 Lux
• Responsive time 15us
• Interface Analog
• Size:22x30mm

Application
• Automatic screen brightness control

RED GRAY

Sample Code
void setup

Serial.begin 9600 // open serial port, set the baud rate to 9600 bps void loop
int val=analogRead 0 //connect grayscale sensor to Analog 0 Serial.println val,DEC ;//print the value to serial
delay 100 ;

Result

Open the serial port monitor, set the baud rate according to the program for 9600.The light intensity around the sensor is different, the received data is also different.The more light, the bigger the data.

Q1. Some general Arduino Problems/ FAQ/ Tips, very good to know. A1. Click the topic link on DFRobot Forum.

Q2. The unit of the output from these sensors is? How can I convert it to LUX? A2. Well, it is only a simple analog sensor that could show you the relationship of the light intensity within its detect range and voltage 0-5V . If you want to transfer the voltage to unit in LUX, then well, it requires that you have a commercial Light Intensity Meter like this that can display LUX info, then you can match the readings to the sensor's analog reading, then you could a map to describe the relationship of voltage and ambient light density.
