Monitoramento e armazenamento da variação de temperatura e umidade em uma residência eficiente

Abstract

In a tropical country like Brazil, most of the states’ climate are predominantly hot and humid, such characteristic meets the problem considered for the proposal of this project: the idea of measuring the ambience temperature in each room of an efficient house located in UFSM for 24 hours. This aims to determine which rooms are the coolest by using researches such as the one of the house facing toward north. The data for this project was obtained via measuring hardware developed mostly by Arduino and its components: (1) first by the use of IoT via WiFi connection with an ESP8266-01, and then (2) with a datalogger system made out of a high precision clock (RTC DS3231), micro SD card reader, four temperature and humidity sensors (DHT22) and two temperature sensors (DS18B20). Data was stored both in off-line backup and in the cloud. Charts and graphics were made to help interpreting the online data which is updated in real time while the off-line backup data is saved in NotePad files (.txt) that can be interpreted more accurately via Excel software macros. Test results were good, however some enhancements like soldering a board instead of using a protoboard must be performed in order to allow this experiment to be more proficiently.
