In our life and production often use a variety of sensors, sensors are actually a big family. Common sensors in accordance with the application can be divided into: pressure sensors, level sensors, temperature sensors, differential pressure sensors, temperature and humidity sensors, soil moisture sensors and so on. Sensors can be divided according to the principle of operation: resistive, capacitive, inductive, piezoelectric, electromagnetic, magnetoresistive, photoelectric, piezoresistive, thermoelectric, nuclear radiation, semiconductor sensors and so on. Sensors can also be divided according to the nature of the output signal: analog sensors and digital sensors. With the progress of science and technology, the development of the Internet, the requirements of the sensor industry is also more and more, the need for sensors to complete the task is also more and more arduous, a large number of researchers are in a hurry to develop new products and innovative technologies. The system architecture of the Internet of Things is generally composed of a perception layer, a transmission layer and an application layer, in which the perception layer is mainly composed of sensors, microprocessors and wireless communication transceivers. Sensors will have a more far-reaching significance as the entrance of data collection.
