About Censor

A sensor is a device that detects various physical quantities or the concentration of substances. Also called detectors, they are incorporated into all electronic devices and play a role equivalent to the sense organs such as the eyes, ears, and nose. It is used not only to detect the object to be measured, but also to determine the next operation of the equipment or to stop the operation of the equipment for safety. In Japanese, it is used in the same sense as Detector (English: Detector), but as a strict definition of the word, Detector is simply for detecting objects to be measured, whereas Sensor is the above-mentioned It refers to an object that shows a specific reaction after being detected, so a detector with some functionality added is called a sensor. Sensors convert physical information such as light and heat into electrical information, and when incorporated into electrical circuits, they enable automatic operation of electrical equipment. For example, an air conditioner is equipped with a temperature sensor. When the air conditioner is set to a certain temperature, the temperature sensor inside the air conditioner detects the temperature. The information is transmitted to the microcomputer, and the air conditioner is operated so that the indoor temperature and the set temperature are equal.
