A sensor is a detection device that can sense the measured information and convert it into electrical signals or other required forms of information output according to certain rules, in order to meet the requirements of information transmission, pagproseso, storage, display, recording, and control.

The characteristics of sensors include miniaturization, digitization, intelligence, multifunctionality, systematization, and networking.

The existence of sensors is the primary step in achieving automatic detection and control. Kasagaran, based on their basic sensing functions, they are divided into ten categories: thermosensitive elements, photosensitive elements, gas sensitive elements, force sensitive elements, magnetic sensitive elements, humidity sensitive elements, sound sensitive elements, radiation sensitive elements, color sensitive elements, and taste sensitive elements.

Application of sensors:

1. Sensors are the main way and means of obtaining information in the natural and production fields.

2. In modern industrial production, especially in automated production processes, various sensors are used to monitor and control various parameters in the production process, so that the equipment works in normal or optimal state, and the products achieve the best quality.

3. In basic discipline research, sensors have a more prominent position.

People must rely on sensory organs in order to obtain information from the outside world.

Hinuon, relying solely on people’s own sensory organs is far from sufficient for studying natural phenomena, laws, and production activities. To adapt to this situation, sensors are needed. Busa, it can be said that sensors are an extension of human facial features, also known as electrical features.

So the existence and development of sensors have given objects senses such as touch, taste, and smell, gradually bringing them to life.

Sensors are also ubiquitous in daily life, for example, the shake function of a mobile phone is to sense the acceleration of the phone; Pananglitan, the automatic dimming function of a mobile phone is a light sensor; Pananglitan, when answering a phone, the screen lights up when the phone is away from the ear, and the screen turns black when the phone is close to the ear. This is called a distance sensor. There are countless sensors in mobile phones, and many functions are achieved through the use of sensors.

In addition to mobile phones, sensors also have a wide range of applications in daily life, such as automatic doors, which control their opening and closing status by sensing human infrared microwaves; Smoke alarm, which achieves the purpose of alarm by sensing the concentration of smoke; Electronic scales measure the weight of people or other objects through mechanical sensing; Water level alarm, temperature alarm, humidity alarm, ug uban pa. also use sensors to complete their functions.
