Abstract
A auto-sensing watering system and regulating method thereof include a integrated infrared sensor for sensing the relative position between objects in the detecting area and the integrated infrared sensor to form an integrated signal; processor connecting to the integrated infrared sensor and performing program operation; and watering controlling element, connecting to the processor to control watering by instruction; wherein, the processor receives the integrated signal to form a flow controlling signal and a temperature controlling signal by performing program operation, and passes the controlling signal and the temperature controlling signal to the watering controlling element to regulate water temperature and flow.
