In smart agriculture, harmful insects can be identified by IoT sensor technology, such as LIDAR. Gas sensors can also be used to monitor the gases needed for crop growth, such as carbon dioxide sensors and oxygen sensors. The purpose of using smart agriculture technologies is to improve production efficiency. Similarly, in the construction sector, the use of AI and IoT's can make a big difference.

Technology upgrades such as miniaturization and equipment durability for construction sites have now resulted in affordable and easy-to-install sensors and controllers. Advances in database and networking solutions allow for real-time data analysis and massive data storage for post-analysis. The advent of machine learning and predictive analytics has brought building automation to a new level.

Today, smart building solutions are becoming more affordable. For example, the total cost of adding IoT controllers and monitors to a building is estimated at just $0.75 per square foot, which is five times cheaper than traditional deployment methods, such as basic building management systems.In the construction industry, developers and general contractors are always looking to reduce costs and speed up construction by using as many IoT solutions as possible, while making more efficient use of limited labor resources.Smart sensors and associated controllers can be used to detect and adjust various building environment indicators. The data acquired enables dynamic resource management and resource utilization as well as residential pattern matching, resulting in improved resource utilization and rental income.

Smart building is a product of the information age. Smart building includes five main functions: building automation, fire automation, communication automation, and office automation, and information management automation, which can be used for air quality sensors, temperature and humidity sensors, etc. As a detection device for intelligent buildings, it is important to use the sensors correctly, and only when used correctly and skillfully the sensors in smart buildings can give full play to their value.
