Abstract
The utility model relates to a pressure detection type water pumping control device. The device is composed of a pressure sensor (1), an amplifying circuit (2), a single-chip microcomputer (3), a displayer (4), a driver (5) and a water pump (6). The pressure sensor (1) detects the pressure of the water level in a water tank, the pressure is converted into a voltage signal, and the voltage signal is sent to the single-chip microcomputer (3) to be processed after being amplified through the amplifying circuit (2). The single-chip microcomputer (3) obtains the height of the water level, outputs a control signal to the driver (5), and controls the work condition of the water pump (6).
