Multifunction sensors are integrated devices capable of detecting multiple physical or chemical parameters simultaneously. These transducers combine various sensing elements into a single unit, enabling compact designs and cost-effective monitoring solutions. Their significance in modern technology stems from their ability to provide comprehensive data acquisition in applications ranging from industrial automation to wearable electronics.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Environmental Sensor | Measures temperature, humidity, pressure, and gas concentration | Smart home systems, weather stations |
| Inertial Sensor | Combines accelerometer, gyroscope, and magnetometer functions | Autonomous vehicles, drones |
| Biosensor | Monitors physiological parameters like heart rate, oxygen saturation | Wearable health devices, medical diagnostics |
