DIY Automatic Water Dispenser Kit

When the infrared sensor module detects that the water cup is placed on the cup holder, it outputs a low-level signal, and the relay drives the water pump to work after receiving the signal. When the water cup leaves the table, the water pump stops working and the water filling is completed.
