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。众所周知,传感器的感觉就像眼睛和耳朵一样,传感器测得的信息(正在感测的数据)应发送到处理器或控制器,以便它们进行处理。
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设备。还将非电物理信号转换为电信号。它提供对所测量的特定输入(可能是物理量)的输出响应。
传感器与传感器的区别:
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. |
