Environmental sensors are used in ​smart city solutions to monitor and analyze various ​environmental factors such as ​air quality, ​temperature, ​humidity, noise levels, and pollution levels. These sensors provide real-time data that helps in making informed decisions for a healthier and more sustainable environment.

Gas sensors, a specific type of environmental sensor, are used to detect and measure the presence of different gases in the atmosphere. They can identify harmful gases like carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and volatile organic compounds (VOCs). Gas sensors are crucial in maintaining air quality, detecting gas leaks, and ensuring the safety and well-being of citizens.

Water management sensors are used to monitor and manage water resources in smart cities. These sensors are deployed in reservoirs, rivers, and water distribution networks to measure and analyze various parameters. They help in monitoring water quality, water levels, flow rates, as well as detecting leaks or anomalies in the water supply system. Water management sensors enable efficient water usage, conservation, and early detection of issues for effective maintenance and planning.
