BH1750FVI Is a Digital Light sensor , which is an digital Ambient Light Sensor IC for I2C bus interface. This IC is the most suitable to obtain the ambient light data for adjusting LCD and Keypad backlight power of Mobile phone. It is possible to detect wide range at High resolution.( 1 - 65535 lx ).
this sensor has some advantages such like :
1) Illuminance to Digital Converter
2) Wide range and High resolution. ( 1 - 65535 lx )
3) Low Current by power down function
4) 50Hz / 60Hz Light noise reject-function
5) I2C bus Interface ( f / s Mode Support )
6) No need any external parts
7) It is possible to select 2 type of I2C slave-address.
8) It is possible to detect min. 0.11 lx, max. 100000 lx by using this function. DataSheet for this sensor will be found here
it's easy to use and connect , so Let's started
We will need :
1) Arduino Board" Uno,Nano,mini .. "
2)BH1750 Breakout .
4)CD4050 Hex Buffer IC , Or 510 Ohm resistor *3
