WATERING SYSTEM AND CONTROL DEVICE
This abstract first appeared for US patent application 18982387 titled 'WATERING SYSTEM AND CONTROL DEVICE
Original Abstract Submitted
A watering system includes a pF sensor, a VWC sensor, and a control device that controls an irrigation operation. The control device controls the irrigation using the pF value detected by the pF sensor and the volume water content detected by the VWC sensor. The control device controls a start timing of the irrigation operation based on the pF value that is detected and a start threshold value. The control device controls a stop timing of the irrigation operation, which is in operation, based on the volume water content that is detected and a stop threshold value. The control device updates the stop threshold value based on fluctuation of the pF value that is detected.
