BH1750FVI Digital Light intensity Sensor Arduino Module AX85 Descripiton: BH1750FVI is a digital Ambient Light Sensor having I2C interface. This IC is the suitable for obtaining the ambient light data. It is possible to detect wide range at high resolution.
SPEC: Chip: BH1750FVI Power Supply: 3.3V - 5V Light Range0 - 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
For example: Night: 0.001--0.02; moonlightnight:0.02--0.3; cloudy indoor:5--50; cloudy outdoor:50--500; Sunny indoor:100--1000; under the sunlight in summer afternoon: about 10*6 power; reading books for intensity of illumination:50--60; home video standard intensity of illumination:1400.
Board Schematic J1 is interfacing connector U1 is voltage regulator which gives out 3V to board from 3.3-5V supply input Q1 is bidirectional data level translator for 5V to 3V level conversion D1 is unidirectional clock level translator for 5V to 3V level conversion Please note that the "addr" Pin is to assign a different I2C address to the sensor.
