What is a radio frequency sensor?alarm sensor Vendor

　　To understand what a radio frequency sensor is, we must first know the difference between RFID technology and sensors-RFID is a radio frequency identification technology, not a sensor. RFID mainly uses the unique ID number corresponding to the electronic tag to identify the marker. In other words, RFID is a simple wireless system with only two basic components. The system is used to control, detect and track objects. The sensor is a detection device that can feel the information to be measured, and can transform the detected and felt information into electrical signals or other required forms of information output according to certain rules to meet the needs of information transmission, processing, and storage. , Display, record and control requirements. It is the first link to realize automatic detection and automatic control. Both are IoT technologies. The difference is that sensor technology can process the sensed items, while RFID is only for identification and has no processing capabilities.

　　The RFID radio frequency identification refers to the use of radio frequency device sensors to read the encrypted electrical storage data in various tags, and then transmit the feedback information to the sensor. The data is sent to the sensor in a wireless manner through the electromagnetic field, so there is no need for sensors and tags. get in touch with.

　　The current radio frequency sensing technology uses an RFID reader to send codes or radio signals to "inquire" a specially designed electroactive RFID electronic tag or trademark. The data storage method is electronic, and the information mode fed back by the electronic label or trademark is very different: some will only generate a serial number, and some can provide a lot of information, such as the production information of the marked item, product parameters , Batch number or stock number, etc.
