The IoT Technology provided in our paper is a very good option for surveillance of the weather parameters in a specified region and make the data visible anywhere in the world. Heavy flood is due to the dynamic alterations in the weather condition. It implements the development of flood monitoring system for storing and retrieving data from the system using NODEMCU ESP8266 where ultrasonic sensor and Led’s are used to alert the authorities regarding the heaviness of water. Soil moisture is an vital part of plant life, which will affect the crop growth and yield directly. It implements the development of soil moisture monitoring using microcontroller and sensor. Earthquake warning system detects the first quivering of a major quake using sensor. Nowadays the count of industries and vehicles are increased ,so the quality of air is poor and it affects the human beings. It is important to analyze the quality of air and the amount of harmful molecules in the air using the field of IOT since it has made a drastic evolution. It develops a system which can detect the amount of toxic particles in air like methane, alcohol, benzene and CO2 using MQ135 sensor. Thing speak stores data in private channel by default. The data can be accessed over internet from anywhere in the world obtained form the embedded system.
