Description
BH1750 is a Digital Ambient Light Intensity Sensor that is commonly used in mobile phones to manipulate the screen brightness based on the environment lighting. This sensor can accurately measure the LUX value of light up to 65535lx.
Pin Configuration of BH1750 Sensor:
| Pin Number | Pin Name | Description |
| 1 | VCC | Power supply for the module can be 2.4V to 3.6V, typically 3.0V is used |
| 2 | GND | Ground of the module, connected to ground of the circuit |
| 3 | SCL | Serial Clock Line, used to provide clock pulse for I2C communication |
| 4 | SDA | Serial Data Address, used to transfer the data through I2C communication |
| 5 | ADDR | Device address pin, used to select the address when more than two modules are connected |
