Ten examples and applications of sensors in life: 1. Stair walkway: electric light touch switch. Function: it can supply power under the contact of human hands or other conductive objects (this is my idea, I don't know if it is. ), which contributes a lot to energy conservation. 2. rice cooker: function: stop heating when it reaches boiling temperature (Curie point). With the hardware support of a certain material, this function can make great progress for human beings! 3. Electronic scale: Function: It can quickly weigh the mass of an object without complicated operation, which is generally more accurate. This is because the pressure sensor and some electronic systems installed under the electronic scale make it possible to weigh the mass quickly and accurately, all thanks to the development of sensors. 4. Electronic thermometer: Function: Simple, rapid and accurate measurement of human body temperature. An infrared sensor is added to the electronic thermometer. Because the intensity of infrared rays emitted by human body is different at different temperatures, we can use this characteristic to use infrared sensors. Touch buttons on 5.MP4: Function: It can be operated without original mechanical pressing, which makes the life of the machine longer, especially the "buttons"! The principle is still unclear, but it is conceivable that it should be the credit of the sensor! 6. Touch screen of mobile phone: Function: There are several kinds, some are point touch and some are face touch, which are different, but the principle should be similar, but the support of hardware materials is different, so there are different operation modes, but the sensor is still playing a role. 7. Electric iron: function: iron clothes and keep them tidy. However, there is a problem to be solved in heating, that is, the problem of heating temperature, so another kind of temperature sensor came into being. When it reaches a certain temperature, there will be power failure to keep the temperature within a certain range, which is similar to a rice cooker! 8. Car weighing: Function: This sensor is used to weigh cars at the ferry. The pressure sensor can accurately weigh very heavy objects in a short time. This is the application of large pressure strain gauge. 9. Automatic door: Function: There will be automatic doors in some important occasions. When people approach, they will automatically open and close the doors according to the situation. These doors should be equipped with human body sensors. Something will happen when someone approaches, so it will automatically open the door. Of course, this is also the result of combining several electronic systems. 10. Toilet urinal: Function: When people are near, there will be water flow, and when people leave, they will flush for the second time. This has made a great contribution to the water saving and cleaning of toilets, which should be the result of the combination of photoelectric sensors and electronic systems. To sum up, we can find that every advanced component should be combined with electronic system to play its role.
