16-bit I2C interface Bright light sensor Ambient Light sensor module VEML7700
Introduction:
This product is a digital ambient light sensor, measuring the intensity of light in different environments, in the serial port monitor with a numerical display, the unit is lx. Its measurement accuracy is high, the range is wide, the detection range is from 0lx to 120klx, the resolution is 0.0036lx/ct.
In terms of circuit, this sensor module supports I2C bus interface, and adopts the design form of Gravity interface, which directly simplifies the user's wiring difficulty.
