| 摘 要： | 温度检测是家用电器中常见的物理量检测，利用温度传感器可以将温度的变化转换为电信号，以此对家用电器进行智能控制。光敏传感器是把光信号转换为电信号的一种换能元件，广泛应用于家用电器的功能控制电路。气敏传感器是用来检测气体的类别、浓度和成分的传感器。它是将气体浓度的变化转换为电信号的传感器。超声波传感器是实现声电转换的装置，所以，又称为超声波换能器。

| Abstract: | Temperature examination is a common physical examination in modem electric appliances. In order to carry the intelligent control on the electric appliances, temperature sensor is used to transform the change of temperature into an electrical signal. Photosensitive sensor which is widely used in control circuit of domestic electric appliances transforms light signal into electrical signal. Gas sensitive sensor is used to examine the category, density and ingredients of the gas. It transfonns the change of density of the gas into an electrical signal. Ultrasonic sensor is an instnunent which transform sound into electricity, therefore, it is also called ultrasonic wave transducer. |
