With the arising of intelligent IoT equipment, we need to collect more data for more complicated decision making. Sensors and external data collection systems have become the activator for the rapid development of IoT industry. The precision of sensors' data collection in the aspects of spatial geography, acceleration, temperature, image and motion has become a key factor to distinguish industry leaders from laggards. Relying on its superiority in positioning chips and combining with the NB-LoT communication technology, Wuhan Mengxin Technology develops a positioning card, which meets the development trends and demands of the market, supports sensor interfaces of various kinds and applies to cold chain logistics management, containers, assets tracking and positioning and other IoT sectors.
