Application of wireless data transmission module in Emdoor rugged tablet terminal

Image
  Technical background The wireless data transmission module is a modular product of the data transmission station, which refers to the high-performance professional data transmission station realized with the help of DSP technology and radio technology. Application The application of wireless data transmission module is very wide, such as wireless meter reading system for water and electricity, hydrological monitoring, oil pipeline monitoring, industrial monitoring, etc. We apply the wireless data transmission module to the rugged tablet terminal. The wireless data transmission module has a variety of ISM frequency bands such as 433MHz, 450MHz, 470MHz, 868MHz, etc. 8, 16, 32, 64 and many other communication channels. 1200bps, 2400bps, 4800bps and other transmission rates. 8N1, 8E1, 8O1 and other data formats. Multiple interface modes such as RS232, RS485, TTL, etc. All of them can be arbitrarily set and selected according to a series of requirements such as transmission distance. ...

Application of LoRa module in Emdoor rugged tablet

Image
  Technical background LoRa, as one of the mainstream technologies in LPWAN (Low Power Wide Area Network), is giving various industries the transformation of the Internet of Things. LoRa is a subset of LoRaWAN, which belongs to a modulation technology of the physical layer. It adopts linear modulation spread spectrum method, which can significantly improve the receiving sensitivity and achieve a longer communication distance than other modulation technologies.The most complete LoRa communication system integrates a complete set of LoRa node modules, gateways and cloud platforms, which can realize end-to-cloud data transmission in one step.   Application   As a large agricultural country, my country is in a critical period of transition from traditional agriculture to smart agriculture. LoRa's long-distance transmission method can realize the accurate transmission of agricultural irrigation, pests, and fertilization status data, comprehensively improve the level of farm pr...
