Light sensor BH1750 and Arduino
Using the module BH1750 we can measure the intensity of light. For the service module we use an Arduino Uno version.
In this example we used the following elements:
Connection BH1750 Arduino:
To operate a generator using a serial interface, connect the circuit with the Arduino in the following way:
| Pin BH1750 | Pin Arduino |
|---|---|
| VCC | 5 V |
| GND | GND |
| SCL | A5 |
| Traffic |
A4 |
Diagram system connection BH1750 Arduino Uno.
Program for Arduino
At the beginning of the library you want to add to the environment of the Arduino (Sketch -> Include Library -> Add .ZIP Library...).
In the example, we used the following code:
#include#include BH1750 czujnikSwiatla; //variable that represents the sensor void setup(){ Serial.begin(9600); //start the monitor serial port czujnikSwiatla.begin(); Serial.println("sensor is Running."); } void loop() { uint16_t lux = czujnikSwiatla.readLightLevel(); //read the value from the sensor Serial.print("the Value of intensity of light: "); //display result on the display consistent Serial.print(Lux); Serial.println(" lx"); delay(500); //delay between consecutive readings }
The result of the program can be viewed on the serial monitor:
