Product description: light intensity sensor BH1750

Digitallight intensity sensoroperating in the range of1 - 65535 Lux (Lux)with resolution of 1 lx or 4 lx depending on the selected mode of operation. It communicates through I2C  interface (TWI), that is, two lines: data - SDA and clock SCL. The module can be used to measure the light intensity both indoors and in the open space. The kit includes a goldpin connector forself-soldering.


Connecting the light sensor

The module has five pins:

The bottom side of the printed circuit board of the sensor BH1750.

  • VCC - supply voltage: 3 V to 5 V.
  • GND - ground of the system.
  • SCL - the clock line of the I2C bus.
  • SDA - data line of the I2C bus.
  • ADD - address selection of the I2C bus, the indication of the low status sets the address to: 0100011, high: 1011100. The pin is by default in the low status.


The product is compatible with Arduino

  • The sensor can be connected directly to the pins of the microcontroller, e.g.Arduinoor minicomputer Raspberry Pi.
  • The user manual is available onour website.
  • Existing library together with the sample code for Arduino can be found onGitHub.
  • In the case of using the Arduino Mega 2560 connected should be pins:SCL with the 21 pinandthe SDA with the 20 pin.
