传感器和换能器的区别

1. 传感器：
传感器是检测环境变化的设备。它可以是温度传感器、压力传感器或湿度传感器。正如我们所知，传感器就像眼睛和耳朵一样感知。传感器测量的信息(被感知的数据)应发送到处理器或控制器，供它们处理。

2. 传感器：
换能器是将能量从一种形式转换为另一种形式的装置。它还将非电物理转换为电信号。它对测量的特定输入(可能是物理量)提供输出响应。

传感器和换能器的区别：

Sensor	Tranducer
A device that convert physical parameters to electrical output.	A device that convert energy one form to another form is know as Transducer.
The word Sensor comes from USA.	The word Transducer comes from Europe.
The uses of Sensor is for sensing element itself.	The uses of transducer is for sensing element and also for circuitry.
In Sensor changes its resistance with temperature.	In Transducers change in resistance to change in voltage.
All the sensors are not transducers.	All Transducers contain a Sensor.
It is a sensor when it responds to a stimulus.	It becomes transducers when connected in a bridge circuit.
It detects change in physical stimulus and turn it into a signal.	It transfers power form one system to another in the same or in different form.
Examples of Sensor: Temperature Sensor, and Proximity Sensor.	Example of Transducer: Strain gauge, and Piezoelectric Transducer.
