Abstract
The guardian is an IoT based helmet device which is cable of sending and retrieving extracted information about the environment by connecting with nearest Wi-Fi networks. The information encompassing the data of six sensors namely, Temperature and Humidity Sensor, Air Quality Sensor, Atmospheric and Pressure Sensor, and UV Index Sensor. These sensors are governed under a microcontroller of an Arduino framework and works under I2C protocol. The NodeMCU microcontroller sends the data over Wi-Fi to a real-time Google Firebase database where it is classifies the sensors based on their type of data. The retrieved real-time information is displayed on a web app user interface in a timely basis. The web application is build using node.js framework to process the real-time data. For front-end design are built using HTML, CSS and JavaScript.
