The Barometric Data Logger is an IoT system (Internet Of Things system) based on Arduino MKR 1000 combined with sensors and modules that points out , processes, displays and sends data relating to the following physics measurements to a cloud: date, time, atmospheric pressure, altitude, photovoltaic panel voltage, brightness, temperature, humidity, dew temperature, heat index. Arduino MKR1000 through a software stored inside it manages the functions of the connected modules / sensors:

BMP280: Atmospheric pressure, ambient temperature and altitude.
DHT22: temperature, environment and humidity.
panel: produced voltage.
RTC: date and time.
LDR: luminosity.
DISPLAY: data display.
WiFi: Internet connection.
An algorithm determines the average temperature (mean between BMP and DHT22), the dew and the heat index. Data processed locally are sent, with a 15-second interval, to a local access point and via the Internet to the thinkspeak cloud where a public account has been created for subsequent reprocessing (graphs, statistics, online diffusion). Through the following link it is possible to consult the data: https: // thingspeak .com/channels/403507. If you want to use your mobile or tablet you have to download an App “ThingSpeak viewer, for example ThingView and configurate it with the 403507 channel.
