# scd40-rusty-pi
![Animation of a web page with CO2PPM, temperature, and humidity values and the CO2PPM value updates every few seconds](images/scd40-web-results-450-gifsicle.gif)
A Raspberry Pi Pico W implementation of a SCD40 based CO2 PPM monitor, it has a
web interface where the current values can be viewed. This is designed to work
with an I2C SCD40 module.
Please note that I am on about day 5 of learning Rust, so this code is not
provided with the intention of it being a correct example to follow. Comments
and feedback are welcomed! This is part of my own learning process.
***This is a work in progress.***
