This is an easy to use light sensor based on the BH1750FVI IC. 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.
Power Supply: 3.3V – 5V
Light Range?0 – 65535 lx(Lux)
Sensor Built-in: 16 bit AD converter
Size(L x W): Approx. 3.2cm x 1.5cm
Direct digital output, bypassing the complex calculation, bypassing the calibration
Close to the spectral characteristics of visual
Widely used to 1-lux high precision measurement
Standard NXP IIC communication
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).
Example Light Ranges:
Under the sunlight in summer afternoon: about 10*6 power
Reading books for the intensity of illumination:50–60
Home video standard intensity of illumination:1400
