The digital 16bit serial output type Ambient Light sensor IC develop by
ROHM semiconductor. The BH1750 IC is a digital Ambient light sensor IC that drives on i2c / IIC bus interface. This IC is the most suitable to obtain the ambient light data for adjusting LCD and keypad backlight power of mobile phone. It is possible to detect wide range at high resolution rated to 1 – 65535 LUX. Mostly used in Mobile Phone, LCD TV, PC, Portable game machine, Digital Camera, Video Camera, PDA, LCD Display.

Step 1: Wiring Diagram

Required Component
Arduino UNO, MEGA, NANO, PRO, DUE, LEO, AVR ESP8266,BH1750 Breakout Modulei2C / IIC OLED Display Module (Optional)Jumper Wires / DuPont WiresSolder Less Bread Board

Step 3: Download the Sketch Code

There are two files can be tested on this project one is with OLED Screen and the other one is without the OLED screen, you can monitor the output via serial port on your IDE.

Nice, thank you for sharing this. Welcome to the site! :)
<p>Thank you mate... :) Two thumbs up..... </p>
