This project proposes to monitor the air temperature, luminosity and humidity, as well as grove temperature and humidity. It proposes too to network this measures which are so readable on the website Actoborad.com
To do, we connect 4 sensors to the Nucleo microcontroller L432KC :
- a luminosity sensor TLS2561 by Adafruit ;
- a humidity and temperature sensor DHT22 by Gotronic ;
- a tempearture probe DS1820 ;
- a humidity sensor Grove - Moisture sensor by Seeed Studio
Measures are done each 10 minutes and are networked via a Breakout TD1208 by Sigfox. As said higher, this one are readable on the website Actoboard.com On this microcontroller is also plugged an OLED Display 128x64 screen which will permanently display the last measures done. Finally, the system is electrically self-sufficent thanks to a 8x20cm photovoltaïc cell and a 1.5Ah battery. They are connected to the Nucleo with a LiPo Rider Pro by Seeed Studio. The system is put in a 3D printed box.
Here is the synoptic of the project :
The code compiled in the microcontroller via os.mbed.com is named 'main.cpp'. The used libraries are available in the followed link, what is our project mbed: https://os.mbed.com/teams/Green-Team/code/greenhouse_proj/
