IOT BASED SMART HOME AUTOMATION AND MONITORING SYSTEM

Abstract

The concept of a smart home is becoming increasingly popular these days. It reduces the amount of physical labor required. In a traditional home, we cannot monitor the electrical appliances, environmental conditions, home security, and cannot control them remotely. Typical residential systems cannot automatically change a systems state in response to a specific scenario. However, this study proposes an IoT-based smart home automation system that works in different modules to automate the entire home. In one module, the system determines the human movement inside the room by using a IR sensor and detects the light level using an LDR sensor. The light level will be adjusted based on the output of the IR sensor. Also, the system operates the fans and heater based on the home temperature and humidity by using an AM2301 sensor. In another module, a flame sensor aids the detection of fire, MQ-135 sensor measures the air quality. In case of fire is detected in the home, the system will also alert the users instantly. To control everything remotely, a mobile application (Blynk App) is used. Converting to a smart home, it can provide security, energy efficiency, and the ability to manage every existing home appliance from a centralized location or remotely. As a result, the system focuses on generating the most excellent possible environmental conditions while requiring the least amount of human effort possible. Beyond everything, it helps in saving time in every manner conceivable.
