BH1750 Light intensity Sensor Module

BH1750 Light intensity Sensor Module is a digital ambient light sensor, IIC I2C communication. Good for arduino light detection. It is a  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 accurate and easier to use 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 more luminous flux in some directions and it can increase the illumination of the target surface. Features:- Direct digital output, bypassing the complex calculation, bypassing the calibration Don’t distinguish between ambient light Close to the spectral characteristics of visual acuity widely use to 1-lux high precision measurement Standard NXP I2C communication agreement Low Current by power down function * 50Hz / 60Hz Light noise reject-function Light source dependency is little.
