Real Time Environmental Data Monitoring with Help of Wi-Fi Module and MQTT Potocol

Abstract: The main objective of this paper is develop, real time data monitoring system for particular location like, home, cities, industries, hospitals, etc., where environmental information of various factors such as temperature, air pressure, humidity, and altitude need to be monitoring and get update with specific time interval. With the help of Wi-Fi module, sensors, and MQTT protocols, we can monitoring real time environmental data over remote location and get updating with it anywhere in world if internet connection present, and if internet connection not present than we can get updating with it in local connection via TCP/IP connection.
