What Does The Sensor Do

Sensors: Detect things or changes in the environment and send information to other electronic devices, usually computer handlers, used in manufacturing and machinery, aircraft and aerospace, automotive, medicine, robotics, and many aspects of everyday life. The applications of sensors have gone beyond traditional temperature, pressure or flow measurement, such as MARG sensors, and more and more sensors are being made into micro-sensors through MEMS technology.

Sensor bias: The output signal is a constant difference from the correct value, then the sensor has an offset error or bias, which is the error of the linear transmission function y-intercept; The sensor has a digital output, then the output is basically an approximation of the measurement attribute, which is called the quantization error; The sensor may be sensitive at some level to properties other than those being measured.

Noise is the random bias of the signal over time. All bias can be divided into systematic error or random error. Micro sensor: refers to at least one physical size in the order of submillimeter sensor. Microsensors are sensors that are small in size.
