LIGHT INTENSITY MODULE

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 a more acurate and easier to use version of the simple foto resistor 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 luxmeter, 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. This sensor can accurately measure the LUX value of light up to 65535lx.

Electrical Characteristics:

• • Interface: I2C
  • Power Supply: 2.4V-3.6V (typically 3.0V)
  • Less current consumption: 0.12mA
  • Measuring Rang: 1-65535lx
  • Accuracy: +/-20%
  • Sensor built 16bitAD converter
  • Small measurement variation (+/- 20%)

Connections:

• • VCC – Power supply for the module can be 2.4V to 3.6V, typically 3.0V is used
  • GND – Ground of the module, connected to ground of the circuit
  • SCL – Serial Clock Line, used to provide clock pulse for I2C communication
  • SDA – Serial Data Address, used to transfer the data through I2C communication
  • ADDR – Device address pin, used to  select the address when more than two modules are connected

Applications:

• • Manipulate brightness in mobile phones/LCD
  • Automobile Headlights on/off control based on surrounding lighting conditions.
  • Used as Ambient light sensors to control the brightness of Display screens.
