KitsGuru New BH1750FVI Digital Light intensity Sensor Module For AVR Arduino 3V-5V Electronic Components Electronic Hobby Kit

This module is based on the light - to - digital converter BH1750FVI, to transform light intensity to a digital signal. BH1750FVI is a calibrated digital light sensor IC that measures the incident light intensity and converts it into a 16 - bit digital number. It can measure ambient light intensity ranging from 0 to 65535 Lux (L). The Lux is an SI unit for luminance and is equal to one lumen per square meter. The BH1750FVI sensor directly gives output in Lux. The spectral response function of the sensor is approximately close to that of the human eye. The sensor output can be accessed through an I 2 C interface. The 7 - bit I 2 C address will be 0 x 23 if the ADDR pin is grounded or 0 x 5C if ADDR is tied to VCC. It is the most suitable to obtain the ambient light data for adjusting LCD and Keypad backlight, it is possible to detect wide range at high resolution, just using this digital light sensor. 1. I 2 C bus Interface2. Spectral responsibility is approximately human eye response.3. Luminance to Digital Converter.4. Wide range and High resolution. ( 1 - 65535 lx ).5. Low Current by power down function.6. 50 Hz / 60 Hz Light noise reject-function.7. Light source dependency is little. ( ex. Incandescent Lamp. Fluorescent Lamp. Halogen Lamp. White LED. Sun Light).8. It is possible to select 2 type of I 2 C slave - address.9. Adjustable measurement result for influence of optical window.10. Small measurement variation ( + / - 20 % ).
