Tutorial: How to Use the BH1750FVI Light Sensor

The BH1750FVI module measures ambient light intensity. Ideal for projects requiring light detection.

What you need

• Arduino
• USB A-MicroB Cable
• Light Sensors

Steps

1. Connect the BH1750FVI module to the Arduino via I2C (SDA and SCL).
2. Install the Adafruit_BH1750 library.
3. Initialize the sensor in the Arduino code.
4. Read the ambient light values.
5. Display the data on the serial monitor.

Example code

Adafruit_BH1750 light = Adafruit_BH1750();
Serial.begin(9600);
light.begin(BH1750_ONE_TIME_HIGH_RES_MODE);
float lux = light.readLightLevel();
Serial.println(lux);

Mini project

Build a home security system that triggers a notification when the light drops below a certain value.

Common mistakes

• I2C connection error
• Incorrect data from the sensor
• Issues with the Adafruit_BH1750 library

Recommended accessories

• Arduino Uno R3
• Adafruit BH1750 Library
• USB Serial Monitor
• Arduino Prototyping Kit

Frequently asked questions

How can I control the lighting?
Use the serial monitor to display the light values.

The sensor is not working.
Check the I2C connection and the installation of the Adafruit_BH1750 library.
