Climate changes and their consequences on the environment and quality of life in Cisterna di Latina (LT)
Weather stations
Arduino is an open source electronic platform that reads an input and returns an output; we can program it using the Arduino Programing Language and the Arduino Software (IDE).
STEM Lab activities
The BMP180 sensor detects pressure. It is a piezoresistive sensor and it consists of a semiconductor material (usually silicon) that changes resistance when a mechanical force such as atmospheric pressure is applied.
The DHT22 sensor consists of two electrodes with a substrate that retains moisture between them. When water vapor is absorbed by sensor, ions are released from the substrate and the conductivity between the electrodes is increased. The resistance variation between the two electrodes is proportional to the relative humidity. Higher relative humidity decreases the resistance between the electrodes, while lower relative humidity increases the resistance between the electrodes.
We used the ESPEP8266-01S WiFi module to send the data to ThingSpeak
ThingSpeak is an open-source IoT application and API for storing and retrieving data from things using https and mqtt protocols over the internet or a local network.
ThingSpeak has integrated support for MATLAB numerical calculation software
The project team measured for 3 months (January - MArch) the values of precipitation and the temperature from the external environment (the moment of temperature measurement was every day, at noon and midnight). At the same time, every day at 10 AM, we used rain gauges to measure the amount of rainwater.
Weather data collected by our team are similar to those coming from the weather stations of Cisterna di Latina: we cannot speak of microclimatic conditions presence.
Weather data was collected for too short a period of time to have statistical significance: our team will keep the built weather stations active in the future and continue climate monitoring
