【Sensor】

《A variety of sensors》

It's just that the bimetal is one plate made of metal sticks to other one of which material is also metal.😚

② A sensor of infrared rays 赤外線.When detecting the infrared rays,voltage is produced.😃

③ A sensor which detects light.Light makes some of them generate electricity,and the light makes its value of resistance change.抵抗値

④ A sensor which detects pressure.Some of switches of limit function when they detect certain pressure,and the pressure makes voltage produces in the other sensor.We call the voltage 圧電素子

⑤ A sensor which detects temperature.When detecting a certain temperature,its value of resistance changes.

As to the sensor which detects light,when becoming dark,it functions automatically.

As for the infrared rays,it's used for a part of what is called a digital camera.The part detects the light,and functions.

The 圧電素子 is adopted for parts which sets on fire of an electronic lighter,or a gas cooker.😃
