A self-propelled nutrient solution detecting and supplying system comprises a main body, a detecting device, and a supplying device. Therein, the main body has a control unit electrically connected to a motor module for propelling the main body to move, a power module, a positioning device for positioning the main body in front of a solution tank, and a storage device having a pH adjuster and an electroconductivity adjuster therein. The detecting device is disposed on the main body and provided with a detecting unit for detecting the pH value and electroconductivity of the nutrient solution. The supplying device is disposed on the main body. The storage device offers the two adjusters into the solution tank through the supplying device for adjusting the pH value and the electroconductivity of the nutrient solution.本發明提供一種自走式養液偵測供給系統,係包含:一本體,其具有一控制單元,以及電連接控制單元之一馬達驅動模組、一電源模組、一定位裝置及一儲存裝置,其中,馬達驅動模組可驅動本體自走,定位裝置可將本體定位於一養液槽前,而儲存裝置裝有酸鹼度調整溶液及導電度調整溶液;一偵測裝置,其設於本體上,且偵測裝置具有一偵測元件,可偵測養液槽內養液之酸鹼度及導電度; 以及一供給裝置,其係設於本體上,而儲存裝置可經由供給裝置供給酸鹼度調整溶液及導電度調整溶液至養液槽中,以調整養液槽內養液之酸鹼度及導電度。300‧‧‧軌道301‧‧‧感應裝置10‧‧‧本體12‧‧‧控制單元13‧‧‧馬達驅動模組14‧‧‧定位裝置15‧‧‧儲存裝置16‧‧‧第一儲存槽17‧‧‧第二儲存槽18‧‧‧第三儲存槽16a、17a、18a‧‧‧泵浦19‧‧‧電源模組20‧‧‧偵測裝置23‧‧‧偵測元件24‧‧‧清洗元件30‧‧‧供給裝置33‧‧‧第一供給出口34‧‧‧第二供給出口35‧‧‧第一管路36‧‧‧第二管路37‧‧‧第三管路40‧‧‧操控面板41‧‧‧開關42‧‧‧時間設定器
