An IoT-Based Real Time Temperature and Humidity Monitoring and Data Logging System Using ESP32

The purpose of this research is to monitor the weather in Mandalay, where temperatures are high, in order to protect children and the elderly from heatstroke. In this research, the weather is monitoring and data logging using TTGO Call ESP 32 with Wi-Fi module, DHT 11 temperature and humidity sensor, 16*2 LCD display with I2C interface. Real Time Clock RTC is used for real time applications. The 16*2 LCD display is used to easily view weather data. The http protocol data logging system is used in this research. The weather data has been data logging to the server by using PythonAnywhere cloud-based platform to view from any location. The temperature and humidity data of the first six months of 2024 were obtained from the PythonAnywhere server, downloaded as a CSV file and analyzed and compared using charts.
