Smart optoelectronic sensors and sensor networks are integrated systems that use optical phenomena to detect changes in the environment, transmit and process data, and automatically adjust measurement parameters. The sensors can record changes in light intensity, colour, and wavelength and detect specific substances or analyse images. Smart optoelectronic sensors are used in environmental monitoring, industrial automation, smart buildings, and biomedical applications. The systems can operate autonomously or as part of larger sensor networks, communicating via wired and wireless technologies.

Mechanism of action
- Smart optoelectronic sensors record changes in optical parameters, such as light intensity, wavelength, or colour, that result from the interaction of light with an object or environment. The changes are recorded by optical detectors that convert the light signal into an electrical signal. The signal is then processed by electronic modules that filter noise, amplify the signal, and perform analysis. Intelligent sensor systems can also analyse data using Artificial intelligence algorithms, detect anomalies, and make real-time decisions, such as triggering alarms, activating actuators, or sending data to central surveillance systems.
