Yunus Emre CENGİZ, Mehmet Duman · European Journal of Science and Technology · 2022
The aim of this study is to measure the temperature and humidity of the environment using a convenient sensor, to process the measured values in a data storage center with a Wi-Fi module internet communication protocol, and to observe & monitor the processed data. In the study, Atmel Atmega328 processor is used as a microcontroller, DHT22 temperature and humidity sensor is used to measure temperature and humidity, and ESP8266 serial Wi-Fi module is used for internet connection. By using the connection between the processor and the computer, the data is transferred to ThingSpeak, which is a data storage server. Parameters and desired parameter units have been determined for the measured values whether locked or open channel which is created according to preferences in ThingSpeak server. The temperature and humidity values are gathered at a specified time interval, and they are graphed over ThingSpeak, along with the time when the measurement take place, and observations are made.
