The Indian Institute of Technology (IIT) Madras has designed a mobile device that is based on IoT technology to monitor the quality of air. The device has several unique features which make it stand out from other air quality monitoring systems. Here are the key highlights of this IoT-based mobile air quality monitoring device:

• The device can monitor the quality of air in real-time, providing accurate data about various pollutants including PM2.5, PM10, CO2, etc.
• It is equipped with a GPS system which helps to provide location-based information about air quality.
• The device is portable and can be easily carried around, making it ideal for use in different locations.
• It is powered by a rechargeable battery which provides long-lasting battery life.
• The data collected by the device is transmitted wirelessly and can be accessed remotely through a mobile app.
• The device is also equipped with sensors that can detect the presence of volatile organic compounds (VOCs), which are often found in indoor environments.
• The device is designed to be affordable, making it accessible to a wide range of users.

Overall, the IoT-based mobile air quality monitoring device developed by IIT-Madras is an innovative solution that can help to address the growing problem of air pollution in India and other countries.
