Multifunction sensors, also called multi-sensors or smart sensors, are multipurpose devices designed to detect and measure multiple physical or environmental parameters simultaneously. These sensors combine the capabilities of several individual sensors into a single compact unit, offering various advantages over traditional sensors, such as reduced complexity, cost savings, and improved data accuracy. Depending on the specific multifunction sensor and application, it can perform several functions accordingly, making it significant for various applications––from healthcare and security to transportation and environmental monitoring. Multifunction sensors are an advanced technology that incorporates essential requirements into a single package, including pressure, temperature, and light, among others. For instance, multi-sensor smoke alarms and multi-sensor fire alarms typically incorporate multiple sensors for detecting smoke and fire in various facilities.
