I. Overview
ZWT- RFW6H02 remote temperature and humidity reader is 6σ RF technology industry applications built on the company completely independent intellectual property rights of innovative technology RFID reader platform for custom development, mainly to increase the temperature and humidity sensor tags, real-time electronic monitoring , writing and reading data capabilities, by supporting RFID electronic temperature and humidity sensor tags can complete cold chain objectives such vehicles or objects locate, identify and alarm, as well as temperature and humidity monitoring alarm.
In recent years, with the "cold chain" continues to expand, active RFID technology in the field of temperature and humidity sensor also will rise. Traditional active RFID tags combined temperature / humidity sensors, which can be collected wirelessly transmit temperature and humidity data upload to the reader, and then transferred to the back-end application systems via wired / wireless manner, completes the target object or environmental temperature and humidity measurements. This measurement can effectively avoid the traditional cable wiring caused large way, maintenance work arduous weaknesses, are choosing to use as more and more users.
ZWT- RFW6H02 remote temperature and humidity reader's leading technology, the whole industrial design and outstanding features make it in cold chain logistics, food safety, environment and other areas to detect a comprehensive competitive advantages, and to create new value for our customers advantages

Fourth, the working principle
Reader operating mode is "passive", when the reader is working properly in the receiving state, receive real-time signal emitted by the electronic tag and the received data is transferred to the background management system.
Relatively speaking, the company's operating mode electronic tag is "active", the tag sends a signal to the reader. Reader with the company's electronic tags work together in the visual environment, the maximum recognition distance (communication distance) can reach 120 meters. In specific applications compared with passive tags to identify long distance has a very big advantage. When the user to identify the length of the distance have different requirements, or the application environment is complex, it can be adjusted and set by the recognition distance attenuation switch on the reader.
Within the effective range of the reader identification, electronic tags run at speeds up to 200 km per hour, it can ensure the stability of identification. This feature is particularly suitable for the exercise of the vehicles and vehicle identification personnel.
