ABSTRACT
The Internet of Thing (IOT) is communication paradigm, embracing connections between physical objects, real world objects and the virtual world. The Internet of Things is a global network that connects physical objects using cloud computing, web applications, and devices that are network dependent and it permits devices to speak with each other, access, store and retrieve data from the Internet, and interact with users, making intelligent, deep, pervasive and perpetually connected environments. Microcontroller based devices are designed to work with IOT Services. The Microcontroller is a versatile device which cannot solely be used to control devices, however can also be used to read data from all kinds of sensors. In this paper we incorporated the use of microcontroller (ESP8266 WIFI module) which acts as interface for temperature and humidity sensor (DHT11). The data collected from this sensor were sent through the internet to a web server which functions as Sensing as a Service cloud server. The data were logged on remote server in real time. Remote monitoring, management and visualization of sensors data were achieved through any internet connected mobile devices. Whenever sensor’s data (temperature and humidity) updated on the cloud server is above certain value, an email alerts were sent to a preconfigured android phone connected to the internet.
Keywords: IOT cloud, Database, Sensors, Cloud computing, Sensing as a Service.
