This sensor measures the volume of water drop and water quantity through an array of traces of exposed parallel wires.
Compared with its competitors, this sensor is not only smaller and smarter but also ingeniously equipped with following features:

• i)smooth conversion between water quantity and analog quantity;
• ii)strong flexibility; this sensor outputs basic analog value;
• iii)low power consumption and high sensitivity;
• iv)directly connected to microprocessor or other logic circuits, suitable for a variety of development boards and controllers such as Arduino controller, single-chip microcomputer, etc.
