IoT-Based Home Automation with Smart Fan and AC Using NodeMCU

In today’s world of the twenty-first century, the Internet of Things (IoT) has emerged exponentially. Many applications are developed in these fields of automation. When it comes to home automation, this concept can be integrated to make it smarter. It makes it easier to access and monitor different home appliances. This paper shows how IoT can be used for smart home automation using NodeMCU and android mobile application. The main focus of the paper is, how the sensor nodes collect the data and pass it to the mobile devices to perform some action as per the user’s commands and provide support to IoT-based mutual controlling between fan and AC based on threshold temperature value.
