This creation discloses a kind of soil moisture control sending device, including humidity sensor, master controller, status display unit, wireless transmitter and gate valve door, wherein master controller connects and controls humidity sensor, status display unit, wireless transmitter and gate valve door. Humidity sensor senses soil moisture, and master controller judges moisture condition, and in humidity deficit, starts gate valve door and supplies after-teeming water. Status display unit can show moisture condition, and moisture condition is sent wirelessly to the receiving unit of distal end wireless transmitter, notifies the user of Smartphone. Status display unit may include light-emitting diode, and therefore, this creation can be sensed, be controlled, adjusting soil moisture, and can directly observe the illumination mode of light-emitting diode and clearly learn the immediate status of humidity in current soil.本創作揭示一種土壤濕度控制發送裝置，包括溼度感測器、主控制器、狀態顯示單元、無線發報器及制水閥門，其中主控制器連接並控制溼度感測器、狀態顯示單元、無線發報器及制水閥門。溼度感測器感測土壤濕度，主控制器判斷濕度狀態，且在濕度不足時，啟動制水閥門而供應補注水。狀態顯示單元可顯示濕度狀態，而無線發報器將濕度狀態以無線方式發送至遠端的接收單元，通知智慧型手機的使用者。狀態顯示單元可包含發光二極體，因此，本創作可感測、控制、調節土壤濕度，且可直接觀察發光二極體的發光方式而清楚得知目前土壤中濕度的即時狀態。
