Domain Model Specification
IoT Level Specification
Home Automation system will follow IOT level 4 specification. Two system will be running parallelly. One is security system and the other is accident alerting system.
In the local environments, data collected from the sensors will be analyzed locally. But when the trigger happens like an unauthorized entry or hazardous situation in the home will update the database with the restricted entry in the cloud.
