BH1750FVI Analog Light Sensor
Description
This is a BH1750FVI light intensity sensor module with built-in a 16 bit AD converter generating digital signal. The data from this module is light intensity in lx (lux meter).
Here are some lx examples :
1） Night: 0.001~0.02;
2） Moonlight night: 0.02~0.3;
3） Cloudy indoor: 5~50;
4） Cloudy outdoor: 50~500;
5） Sunny indoor: 100~1000;
Mainly Features
1、Switchable Voltage: 4.5V~6V or 3.3V
2、I2C bus Interface with 2 alternative address (f/s Mode Support)
3、Spectral responsibility is approximately human eye response
4、Wide range and High resolution (1 ~ 65535 lx)
5、Light source dependency is little. (ex. Incandescent Lamp. Fluorescent Lamp. Halogen Lamp. White LED. Sun Light)
6、 Adjustable measurement result for influence of optical window (It is possible to detect min. 0.11 lx, max. 100000 lx by using this function.)
7、The influence of infrared is very small.
8、Small measurement variation (+/- 20%)
Specification
Operation on this module is pretty easy. We supply sample code.
Address of this module can be changed. By default, the address is "0100011". You can connect the solder bridge in the ADDR box as shown below. Then the address becomes "1011100".
You can also do other configurations. For more information, you can refer to the datasheet.
