WL- INK SHENZHEN WLINK TECHNOLOGY CO., LTD Background Smart agricultural irrigation system combines 4G/3G/NB-IoT network and automatic control technology to implement precision irrigation, based on actual water requirement of crops and information technology to improve irrigation accuracy. The system can automatically sense when and how long the irrigation is needed. Not only the Smart agricultural irrigation system can improve the utilization rate of water resources and alleviate the contradiction of increasingly tense water resources, but also increase the crop yield and reduce the cost of agricultural products. WLINK Solution Equipping with WLINK 4G/3G/NB-IoT modem \ RTU enable the system send farm meteorological data and soil moisture data to the data center over wireless network. The data center will analyze the data and compare it with the special irrigation threshold. When data is up to irrigation threshold, the data center will send irrigation command to WLINK Cellular Modem \ RTU to turn on solenoid valves and startup the pump to irrigate the crops according to the preset irrigation mode.
