Electronics includes physics, engineering, technology, and applications that deal with the emission, flow, and control of electrons in vacuum and matter. It uses the most active devices to control the flow of electrons through amplification and rectification, which distinguishes it from classic electrical engineering, which uses passive effects such as resistance, capacitance, and inductance to control the flow of current. Electronic products have had a significant impact on the development of modern society.

The identification of electronics in 1897, and the subsequent invention of the vacuum tube that can amplify and correct tiny electrical signals, opened up the field of electronics and the era of electronics. This distinction began around 1906, when Lee De Forest invented the triode, which made it possible to use non-mechanical equipment to electrically amplify weak radio and audio signals.

Nowadays, the use of electronic products is a very important part of our daily lives. A world without electronics. From cooking to washing, exercising, and listening to music, everything uses electronics in one form or another. We live in an electronic age, where machines can do all human work more efficiently light.

Consumer Electronics

We use many electronic applications every day. these are called consumer electronics products. These are mainly electronic products used by ordinary people on a daily basis.

Office equipment, such as calculators, personal computers, fax machines, printers etc.

Household appliances, such as washing machines, refrigerators, microwave ovens etc

Audio and video systems, such as VCR, headphones, DVD players, wireless speakers etc

Storage devices, such as jukeboxes, optical playback,portable MP3 players

Modern consumer electronic devices such as smartphones, barcode scanners, ATMs etc

Medical Electronics

Due to the knowledge of electronics, many physiological analyses and do data recording are under development. These tools treats and diagnose diseases. Medical equipment includes

Stethoscope, listens to the internal noises in your body.

A defibrillator that triggers an electric shock to the heart muscles

The respiratory monitor reports the patient’s blood flow, respiration, heart rate etc

The blood glucose meter measure blood glucose levels.

A pacemaker that reduces and increases the number of heartbeats.

Meteorological Electronics

Environmental monitoring is carried out through a large number of automatic weather stations and sensors. Some of them are

Barometer Mostly Used to predict good or bad weather.

Anemometer An anemometer helps to measure wind speed and direction.

Inclined bucket rain gauge This instrument is useful for rain

Drifting buoys Measure the temperature,pressure in the ocean

Data Logger store data collected by multiple sensors, such as wind speed, temperature etc

Conclusion

Today, electronic devices play an important role in our daily lives. They become our help, our friends, and possibly our enemies. I have interest in electronic equipment. I want to study it in depth because my family and some of my classmates do it. They were tortured by mobile phones and computers, and they went to bed very late. I want to find the right way to use electronic equipment so that we can benefit from it without adverse effects.

With the development of economy and the progress of science and technology. Electronic products are becoming more and more popular in production and people’s lives, providing great convenience for production and people’s lives.

Electronic products force people to use the shape of letters. As a more convenient way of communication using mobile phones, telephones and even Internet chat software. You can use the Internet to negotiate business, represent your relatives and friends in the distance. You can conduct video chats to narrow the distance between each other. Today, this change is related to the development of science and technology, the popularization and intelligence of electronic products, and people communicate with each other more freely and quickly.
