BH1750 Digital Light Intensity Sensor Module , It is a digital Ambient Light Sensor having an I2C interface. This IC is the suitable for obtaining the ambient light data. It is possible to detect a wide range of light intensity at high resolution. It is a popular IC with ready libraries and sample codes available, which makes it easy to use in custom projects.

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 or additional circuitry. This is a more accurate and easier to use a version of the simple LDR which only outputs a voltage that needs additional data in order to obtain meaningful data. The sensor outputs light values directly in Lux (Lx).
