Composite Sensitive Function Of Smart Sensor

We observe the natural phenomena around us. Common signals include sound, light, electricity, heat, force, and chemistry. Sensitive component measurement generally adopts two methods: direct and indirect measurement. The smart sensor has a composite function, can measure multiple physical quantities and chemical quantities at the same time, and give information that can more comprehensively reflect the law of matter movement. For example, the composite liquid sensor developed by the University of California can measure the temperature, flow rate, pressure and density of the medium at the same time. The composite mechanical sensor can simultaneously measure the three-dimensional vibration acceleration (acceleration sensor), velocity (speed sensor), displacement (displacement sensor), etc. of an object at a certain point.
