The controller and sensor of the brushless DC water pump are usually integrated in the water pump module, and can also be connected separately to realize the control and monitoring of the water pump through the connection with the motor, power supply and other components.

The controller is an important part of the brushless DC water pump. It is mainly responsible for controlling the speed and steering of the motor, and realizing the adjustment of flow and crime. The controller is usually composed of microprocessors, circuit boards, capacitors, resistors and other components, and may realize complex control and automation functions through programming and software algorithms. For example, the controller can change the voltage and frequency of the motor to adjust the flow and pressure, and can also realize functions such as automatic start and stop, reverse control, and fault diagnosis through integrated control logic and sensors.

The sensor is another important part of the brushless DC water pump. It can monitor the flow, pressure, temperature, humidity and other parameters of the water pump, and feed the data back to the controller for processing. Sensors are usually composed of pressure sensors, flow sensors, temperature sensors, etc., and can be connected to the controller through cables or wireless communication. For example, the pressure sensor can monitor the outlet pressure of the pump, the flow sensor can monitor the flow of the pump in real time, and the temperature sensor can monitor the temperature of the pump in real time. These data can be used for the control and automation functions of the controller.

In short, controllers and sensors are important components of brushless DC water pumps. They can realize automatic control, monitoring and fault diagnosis of water pumps, improve the stability and reliability of water pumps, and provide important support and guarantee for various application scenarios.
