This project demonstrates an IoT based Temperature and Humidity Monitoring System. A sensor device (such as ESP8266 / ESP32 with DHT11 or DHT22 sensor) collects environmental data and sends it to a cloud server through the Internet.
The data is stored in a MySQL database and displayed on this web dashboard in real time. The dashboard shows the latest sensor readings and calculates daily average values for temperature and humidity.
This system can be used for:
The page automatically refreshes every 30 seconds to display the latest data.
