Internet of Things (IoT) is network transfer data without human to human and human to machine communication. This project based on IoT (Internet of Things) for Home Automation. Home Automation is a collection of sensor Controller by microcontroller. Using Microcontroller, we can send data into the cloud server then we can share information on Cloud server and mobile app. we use cloud server as Ubidots. The monitoring value from the home sensor like Gas, Flame, Sound and Temperature to the cloud server (ubidots) and app. Main motivation of this project is to alert message and mail to Smartphone on any abnormal condition. This project is designed to reduce data transmit, reduce time, cost effective and easy to use.
