The traditional method of temperature monitoring is to use analog sensors such as thermocouples, thermal resistors, and semiconductor PN junctions to obtain digital signals representing temperature values through signal sampling circuits, amplifying circuits, and AD conversion circuits, and then use microprocessors or DSPs to obtain digital signals that represent temperature values. deal with. The measured temperature signal starts from the non-electrical analog quantity received by the sensitive element and converts it into a digital signal that can be processed by the microprocessor. Designers have to consider many circuit links, and the number of components in the corresponding temperature measuring device is difficult to reduce. Consequently, the reliability and volume miniaturization of the product are affected. As a result, the entire detection system will have a large deviation, and the stability and anti-interference performance are poor. It is very meaningful to design a wireless temperature monitoring system with simple system structure, strong anti-interference ability, and suitable for on-site temperature measurement in harsh environments.
