Sensors and sensor networks for smart buildings and cities are monitoring systems that collect, process, and transmit data on various environmental parameters, such as temperature, humidity, air quality, lighting levels, and the presence of people. The sensors can be equipped with advanced optoelectronic components for motion detection, image analysis, and emissions monitoring. Sensor networks communicate via wired or wireless technologies to create intelligent management systems for buildings and urban spaces. Major applications include building automation, intelligent lighting systems, security monitoring, energy management, and emergency response systems.

Importance for the economy
Sensor systems for smart buildings and cities are crucial to creating sustainable, safe, and energy-efficient urban spaces. By monitoring environmental parameters, it is possible to reduce energy consumption, improve air quality, and enhance public safety. The sensors also enable better management of city infrastructure, resulting in reduced operating costs and faster response to emergencies. The systems have great potential in the construction sector, real property management, energy, and the developing concepts of smart cities.

Mechanism of action
- Sensor systems in smart buildings and cities are based on constant monitoring of environmental parameters and provision of real-time data to central management systems. Optical sensors record changes in light intensity or motion, while environmental sensors analyse air composition, humidity, and temperature. The collected data is sent to a central unit for processing and analysis. Depending on the results, the system can automatically adjust building parameters, such as lighting, heating, ventilation, or trigger alarms, when a threat is detected. With integrated communication networks, the sensors can operate in large spaces, such as entire buildings or cities, providing comprehensive automation and energy efficiency improvements.
