Anonymous users2024-01-24(1) Infrared remote sensing can not only perceive visible light, but also perceive the infrared rays emitted by objects The valves of the inductive flusher in the toilet and the water inlet and drain valves of the automatic washing machine use infrared remote sensing technology
2) Due to the poor contact at the line connection, the obstruction effect of current passage increases, so the resistance increases;
The resistance of the line connection increases relative to other places, according to Joule's law Q=I2Rt, more heat is generated under the same current and time, so it leads to an increase in the local temperature, and the temperature at the contact increases, so that the resistance at the contact is further increased, and more heat is generated, so that the temperature rises rapidly, and the temperature is too high to easily cause a fire
So the answer is: infrared; become larger; become larger;
Infrared remote sensing can not only perceive visible light, but also perceive the infrared rays emitted by objects The valves of inductive flushes in the bathroom, and the water inlet and drain valves of automatic washing machines use infrared remote sensing technology >>>More
Hello, this is like an automatic perfume spraying machine, it is easy to buy very, when is a block, the function is to sterilize, deodorize and add fragrance to the indoor air, depending on the quality of the one you buy, it can be timed, there is also a sense of light, etc., you Taobao search a lot of a lot of it will come out. Think about it!
The toilet infrared sensor is realized by connecting the solenoid valve through the infrared sensor switch. >>>More
Didn't you see it on the TV show?
Around the sensor hand dryer, bacteria are the most abundant due to the influence of temperature. Although hands can be dried, the bacteria sticking to them have increased dramatically. >>>More
Go to the hardware store and tell them to ask for a water pipe plug, they should know the specific caliber.
