The Main Functions Of Sensors

The function of sensors is often compared to the five major sensory organs in humans:
Photosensitive Sensors - Visual
Sound sensitive sensors - auditory
Gas Sensor - Olfactory Sense
Chemical Sensors - Taste
Pressure sensitive, temperature sensitive, fluid sensors - tactile
Classification of sensitive components:
Physics, based on physical effects such as force, heat, light, electricity, magnetism, and sound.
Chemistry, based on the principles of chemical reactions.
Biological, based on molecular recognition functions such as enzymes, antibodies, and hormones.
Usually, according to their basic sensing functions, they can be divided into ten categories: thermal sensitive 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 (some people have classified sensitive elements into 46 categories).
