# LuminanceMeter
A simple hardware project that features an Ambient Light Sensor and 0.96" OLED screen controlled by a XIAO-RP2040 microcontroller to measure light level and display it interms of lux (luminance).


## Features

- **Uses Sensor to read luminance**
- **OLED Display (128x64):** displays ambient light level in lux.  
- **Portable:** With a CR2032 battery holder you can take it anywhere after flashing it with the firmware . (You hold the button to measure luminance if you are using battery to power it.)
