The microcontroller was born in the 1970s and has been in development for over fifty years. From the initial 4-bit microcontroller to the current 8-bit microcontroller, 16-bit microcontroller and 32-bit microcontroller, as well as in the high-end field of microcontroller 64-bit microcontroller. The scope of application of microcontroller is also gradually expanded, nowadays, the application of microcontroller covers almost every corner of people's daily production life, where there is the shadow of microcontroller. Today's article will provide a detailed answer to the question of what are the application areas of microcontrollers.
       What are the application areas of microcontrollers?
　　With its low power consumption, strong control functions, high reliability and advanced degree of significant advantages, the microcontroller has become a practical tool in the field of science and technology, and is also a powerful assistant to people's lives. Its application area has been expanding, according to the use of the introduction of the following major application areas

1. Household appliances

　　You may not believe it, but at present the average resident can say that 99% of electrical appliances are used in the microcontroller. For example, rice cookers, refrigerators, fans, washing machines, air conditioners and LCD TVs and other common household appliances, as well as a variety of audio equipment, niche weight scales, nebulisers and so on will be used microcontrollers.

2. Medical equipment field

　　Microcontrollers are also widely used in the field of medical equipment, such as thermometers and electronic thermometers in the low-end field, and various analyzers, respirators, monitors and ultrasound diagnostic equipment in the high-end field.

3. Industrial control field

As microcontrollers can form a variety of control systems and data acquisition systems. Therefore, it is widely used in the intelligent management of factory lines, intelligent control of lifts in buildings and various alarm systems, and can also be networked with computers to form secondary control systems.

4. Intelligent instrumentation field

　　Microcontroller has the advantages of small size, low power consumption, strong control function, flexible expansion, micro-miniature, easy to use, etc. It is combined with various types of sensors to achieve a variety of physical quantities, such as voltage, power, frequency, humidity, temperature, pressure, etc.. The digitalisation, intelligence and miniaturisation of the instrument through microcontroller control makes it more powerful than using electronic and digital circuits. High precision measuring instruments (energy meters, oscilloscopes, various analytical instruments).

5. Computer network communication field

　　By having a communication interface, the microcontroller is able to communicate directly with the computer for data communication. For example, mobile phones, remote monitoring switches, automatic communication call systems, wireless intercoms and so on are realized by the microcontroller intelligent control.

6. Modular applications in large appliances

　　Some special microcontrollers are used to achieve specific functions and can therefore be modularly applied to different circuits without the user knowing their internal structure. Music integrated microcontrollers, for example, have seemingly simple functions that are miniaturised on a purely electronic chip (as distinct from the principle of magnetic tape) and require complex principles similar to those of a computer. For example, the music signal is stored in memory in digital form (similar to ROM), read by the microprocessor and converted into an analogue music electrical signal (similar to a sound card).

　　Of course, the application areas of microcontrollers go far beyond the above. In addition to the above six main areas, microcontrollers also have a very wide range of uses in industry, finance, education and defence and aviation. With the development of 32-bit and 64-bit microcontrollers, the computing performance of microcontrollers has been greatly improved, and in the future, the application areas of microcontrollers will continue to expand!
