The AN-223 wireless data collector adopts LoRa. The AN-223 wireless data collector is a data acquisition terminal based on LoRa technology independently developed by Weichuan Technology. The acquisition terminal is mainly used for RS485 data acquisition and is located at the node layer of the entire LoRa network. Adopting the LoRaWAN standard protocol and providing RS485 communication interface for external use, the configuration is flexible, making it convenient and fast to connect various sensors, shortening the sensor docking cycle and research and development costs. Based on LoRa spread spectrum communication technology, coupled with high-performance external antennas, it has superior RF performance. The product shell is sturdy and durable, with an IP65 protection level. It adopts track and wall mounted installation, and the installation method is simple.
