What are Smart Sensor Systems?
Smart sensor systems are advanced devices that integrate sensing capabilities with data processing and communication technologies. They are designed to monitor, analyze, and respond to changes in their environment. In the context of catalysis, these systems are essential for real-time monitoring and optimization of catalytic processes.
How Do Smart Sensor Systems Work in Catalysis?
Smart sensor systems in catalysis typically involve a combination of chemical sensors, data acquisition modules, and advanced software algorithms. These systems measure various parameters such as temperature, pressure, concentration of reactants and products, and other physical and chemical properties. The data collected is processed and analyzed to provide insights into the catalytic reactions, allowing for optimal control and efficiency.
