The Internet of Things (IoT) is a worldwide network of "smart gadgets" that can interact with people and other systems. It can sense and connect to their surroundings. Air pollution is a significant problem nowadays. The present monitoring techniques have poor accuracy, sensitivity and need for laboratory testing [1]. We have proposed a three-level air pollution monitoring system to address these issues with current regulations. Gas sensors, the Arduino Integrated Development Environment (IDE), and a Wi-Fi module form the foundation of the IoT kit. Gas sensors gather information from their surroundings and send it to the Arduino IDE. It uses the Arduino Wi-Fi module to send IDE data to the cloud. We’ve also created the Android application IoT-Mobair, which enables users to access the pertinent cloud-based air quality data [3]. When the user arrives at their location, the pollution level is graded throughout the trial, if it is too high an alarm is displayed. Air quality data may also be used to predict future air quality index (AQI) values
Internet of Things (IoT) plays a vital job in interfacing the encompassing environmental things to the organization and made easy to access those un-internet things from any far-off location. The human death because of heart attack is increasing day by day. Because of today's human way of life, eating habits, irregular daily schedules, the heart attack issue is becoming predominant. So here we planned a project which enables early recognition of heart attack and provide medical facilities pronto. This mainly centers around early detection of heart attack which thus lessens the human death rate because of heart attack. And by utilizing this gadget, one can screen heart rates which also assists with distinguishing heart attack.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
