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, pemprosesan, penyimpanan, paparan, rakaman, dan kawalan.

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

The existence of sensors is the primary step in achieving automatic detection and control. Biasanya, 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.

Namun begitu, 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. Oleh itu, it can be said that sensors are an extension of human facial features, also known as electrical features.

Jadi kewujudan dan perkembangan sensor telah memberikan objek deria seperti sentuhan, rasa, dan bau, secara beransur-ansur menghidupkan mereka.

Sensor juga terdapat di mana-mana dalam kehidupan seharian, contohnya, fungsi goncang telefon bimbit adalah untuk mengesan pecutan telefon; Contohnya, fungsi pemalapan automatik telefon bimbit ialah sensor cahaya; Contohnya, apabila menjawab telefon, skrin menyala apabila telefon jauh dari telinga, dan skrin menjadi hitam apabila telefon dekat dengan telinga. Ini dipanggil sensor jarak. Terdapat banyak penderia dalam telefon bimbit, dan banyak fungsi dicapai melalui penggunaan sensor.

Selain telefon bimbit, penderia juga mempunyai pelbagai aplikasi dalam kehidupan seharian, seperti pintu automatik, 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, penggera suhu, humidity alarm, dll. also use sensors to complete their functions.
