Here to make an IoT ESP8266 Based Lux Monitor or Light Gauge using BH1750 Ambient Light Sensor & Gauge Widget it an Ubidots delivered end-to-end IoT solutions. We can monitor the Light intensity of a particular location from anywhere in the world. For that, we need to use some hardware like NodeMCU ESP8266 & BH1750 Ambient Light Sensor Module, IoT cloud platform.
BH1750 Ambient Light Sensor
BH1750 is a digital ambient light sensor that is used commonly used in mobile phones to manipulate the screen brightness based on the environment lighting. This sensor can accurately measure the LUX value of light up to 65535lx.
Power Supply: 2.4V-3.6V (typically 3.0V)
Less current consumption: 0.12mA
Measuring Rang: 1-65535lx
Communication: I2C bus
Built in A/D converter for converting analog illuminance in the digital data.
Very small effect of IR radiation
Highly responsive near to human eye.
