Final Project


For my final project I decided to make a plant pot, with an integrated CO2 sensor that allows to evaluate the quality of the air inside our houses.

The electronic components are used: Co2 sensor, microcontroller and bluetooth module which are modular boards connected to each other.

The bluettoth module allows to send the air quality data to the person through an Mobile Application
