DLight Unit is a Digital Ambient Light Sensor. Adopts BH1750FVI sensor (I2C interface), integrates 16-bit ADC, supports wide-range LUX and high resolution (1 - 65535 LX). Compact in size, and low power consumption. Suitable for various light sensing applications.
Support I2C interface (addr: 0x23)
Illumination digital conversion
Support light source variations (incandescent, fluorescent, halogen, white LED, sunlight, etc)
Question: What is the difference between a digital ambient light sensor and a photointensity detection sensor? (Can the brightness of the computer monitor be measured?) )
-Illuminance:refers to how much light I get somewhere, and his unit of measurement is lux.
Brightness: The brightness of the recognition seen by the human eye. The unit of measurement is candela per square meter (cd/㎡).
Illuminance and brightness， one refers to how much light is obtained per unit area, and the other refers to how bright it looks per unit area.
Brightness is related to reflectivity, and the reflectivity of the palm of the hand is not the same, resulting in the difference between brightness and darkness.
So the output of the digital ambient light sensor is the amount of light; The light source can be: incandescent lamp, fluorescent lamp, halogen lamp, white LED, sunlight；
The output of the photosensitive intensity detection sensor is the analog value of the brightness of the light; It can be divided into ultraviolet photoresistors, infrared photoresistors, visible photoresistors, here our sensor is visible light photointensity detection sensor。
