the importance of home security has increased because the Internet of Things (IoT) devices are used more frequently in home automation. The possibilities to design and use a wide range of features for an IoT-based security system are endless, despite the fact that the field of smart home security systems has seen several major advancements over the previous years. Our proposed project introduces a low-cost Internet of Things-based home automation and security system that gives the user full remote control over the home applications. Our Android application interprets the data acquired from sensors like DHT11, MQ2, Fire sensor, Ultrasonic sensor, and PIR sensor using Google's Firebase.
