LEVEL SENSOR SYSTEM USING LOW-POWER WIDE-AREA NETWORK

摘要

The level sensor system using the LPWAN according to an embodiment of the present invention is a level sensor that generates feed stock information by measuring the amount of feed in a feed storage, and feed stock information generated by the level sensor is LPWAN (Low-Power Wide). -Area Network) including an LPWAN modem IoT converter transmitted through, and an LPWAN sensor installed inside the feed storage; A feed ordering server that receives the feed stock information to determine whether or not there is a shortage of feed in the feed storage, and if it is determined that the feed storage is insufficient, in connection with a feed company to process a feed order for a corresponding farm; And an AP gateway that is communicatively connected to the LPWAN sensor through the LPWAN and communicated with the feed ordering server through the Internet, and relays the feed inventory information between the LPWAN sensor and the feed ordering server.
