Project 8: BH1750 Digital Light Intensity Module
(1)Description:
The main component of this sensor is chip
BH1750FVI which is an integrated chip for digital
light intensity.
As shown in the picture below, BH1750 is
composed of a photodiode, an operational amplifier, an ADC acquisition, a
crystal oscillator, etc. The photodiode converts the input optical signal into
an electrical signal through the photovoltaic effect. After being amplified
by the operational amplifier circuit, the voltage is collected by the ADC,
