Smart sensors are advanced sensors that are equipped with data processing modules and have the ability to communicate with other devices, which can provide not only basic information about environmental parameters, such as temperature, humidity, and pressure, but also analyse data in real time, detect patterns, and respond to changing conditions. Compared to traditional sensors, smart sensors are able to make decisions based on processed data and collaborate within a network of IoT devices. They can be used in smart buildings, energy management systems, industry, and health care, helping to increase efficiency and improve system safety.

Type of technology
Description of the technology
Basic elements
- Sensor element: A module that detects changes in the environment, such as changes in temperature, pressure, and gases, and generates an electrical signal.
- Microprocessor: Built-in real-time data processing chip capable of analysing and preprocessing signals.
- Communication module: An interface that enables communication with other devices via various protocols, such as Wi-Fi, Bluetooth, Zigbee, and LoRaWAN.
- Software: Built-in data processing algorithms that enable intelligent analysis and decision-making based on predefined rules.
- Power supply: Battery, photovoltaic, or harvesting energy systems.
Industry usage
- Smart buildings: Energy consumption monitoring, motion detection, and lighting control.
- Health care: Body-worn sensors to monitor patients’ vital signs.
- Industry: Monitoring machine status and environmental conditions in real time.
- Agriculture: Monitoring soil moisture and weather conditions to optimise irrigation.
- Logistics: Tracking transport parameters to ensure the safety of goods.
Importance for the economy
Smart sensors are crucial to the development of the Internet of Things as they enable the integration of the physical world with the digital space. They make it possible to monitor, analyse, and optimise processes in real time, which results in increased efficiency in sectors such as industry, agriculture, health care, logistics, and energy management. The use of smart sensors in industry makes it possible to monitor the condition of machines, predict failures, and optimise production, helping to reduce operating costs and minimise losses. In city management, smart sensors support the creation of modern transport, traffic management, and public safety systems.

Mechanism of action
- Smart sensors detect specific environmental parameters, process signals in real time, and transmit processed data to a central system or other IoT devices. The sensor records changes in the environment, such as changes in temperature and vibration, and converts them into an electrical signal. Then, a microprocessor analyses the data and decides what information to send to the network. Depending on the configuration, the sensors can perform local calculations, filtering out irrelevant data, and monitor changes in the environment, adapting their operation to current conditions. With their communication and analysis capabilities, they can act as decision-making nodes in larger IoT systems.
