ماژول سنسور شدت نور BH1750FVI

This is a BH1750 light intensity sensor breakout board with a 16 bit AD converter built-in which can directly output a digital signal, there is no need for complicated calculations. This is more accurate and easier to use the version of the simple LDR which only outputs a voltage that needs to be calculated in order to obtain meaningful data. With the BH1750 Light Sensor intensity can be directly measured by the LUX Meter, without needing to make calculations. The data which is output by this sensor is directly output in Lux (Lx). When objects which are lighted in homogeneous get the 1 lx luminous flux in one square meter, their light intensity is 1lx. Sometimes to take good advantage of the illuminant, you can add a reflector to the illuminant. So that there will be a more luminous flux in some directions and it can increase the illumination of the target surface.

BH1750 ambient light sensor can be interfaced with Arduino through I2C bus pins such as SDA and SCL that are A4 and A5 pins of Arduino Uno.

I2C Interface

GND: Pin1 is a ground pin.

ADD: It sets the address of the I2C interface. Connect this pin either to the ground or Vcc after selecting the address via I2C.

SDA: Serial Data Address pin transfers data through the I2C bus.

SCL: It is a serial clock pin for communication through the I2C interface.

Vcc: Apply 3.3V-5V at this pin.
