BH1750 FVI Light Intensity Sensor

The GY-302 BH1750 module is a digital lighting sensor. This module includes a BH1750 digital lighting sensor for measuring luminous flux (illuminance) from the Rohm Semiconductor company. It has an internal 16-bit converter, so it provides a digital output in I2C format, which allows it to be easily connected to a microcontroller such as Arduino. Its operation is better than that of a Photo-Resistor (LDR) sensor, since it is not necessary to perform voltage conversions to obtain interpretable data. It is ideal in applications where it is required to determine the ambient lighting and can be used, for example, to adjust the brightness of LCD screens, keyboards, automatic lighting, etc. The BH1750 delivers luminous intensity directly in Lux (Lx) units.

Features:

• Voltage: 3.3-5VDC.
• Power: 260mW.
• Operating current: 120µA - 190µA.
• Communication: I2C with the ability to select between 2 addresses.
• Measurement range: 1-65535 lux (16bits).
• Spectral response similar to that of the human eye.
• Perform illuminance measurements and convert the result to digital.
• Low power consumption mode
• Noise rejection at 50/60 Hz.
