IOT-based Output of DHT11 and Ultrasonic Sensor on Web Server

Abstract

In this paper, we’ve shown how to use a DHT sensor to display sensor readings on a web page. DHT11 is a Temperature and Humidity Sensor that outputs a digital signal. We've given two examples: a basic web server and an asynchronous web server with automatic updates. In future, from this project we can also develop our project in chip size using advanced technologies and use it anywhere, at any time. It can be useful for storing and maintaining data records in the cloud and retracing them at any time and from any location by the doctor or patient while online.
