What is an automatic door sensor?
It is understood that the automatic door sensor, also known as the induction device or sensor, is a detection device that can sense the measured information, and can transform the sensed information into electrical signals or other required forms according to certain rules. Information output, to meet the requirements of information transmission, processing, storage, display, recording and control, usually consists of sensitive components and conversion components:
*Sensitive element refers to the part of the sensor that can be measured directly (or in response).
*Conversion element refers to the part of the electrical signal that can be felt (or responded) by a more sensitive element in the sensor, and is converted into an electrical signal that is transmitted and/or measured.
When the output is a specified standard signal, it is called a transmitter. It is the first link to realize automatic detection and automatic control. Sensor detection has the characteristics of accuracy, sensitivity and durability, so it is widely used in automatic doors.
