Pressure sensors play a crucial role in small inflatable pump PCBA, mainly reflected in precise measurement, automatic control, safety protection, data feedback and display, etc., as follows:

Accurate measurement of pressure values: The core function of the pressure sensor is to accurately measure the pressure in the air circuit of the inflatable pump in real time. Whether inflating car tires, bicycle tires or various inflatable equipment, it is necessary to accurately know the current pressure condition. It can convert the felt pressure signal into electrical signals, provide basic data support for the inflation process, and ensure the accuracy of the inflation volume.

Implements automatic control function: The pressure sensor provides feedback for the automatic control of the inflatable pump. After setting the target inflation pressure, the pressure sensor continuously monitors the actual pressure value and transmits the signal to the microcontroller. When the pressure reaches the set value, the microcontroller controls the motor to stop working according to the signal of the pressure sensor, thereby automatically stopping inflation; on the contrary, when the pressure is lower than the set value, the motor controls the motor to start inflation, so that the inflation process does not require frequent manual intervention, which improves the automation and convenience of inflation.

Ensure safe operation: During the inflation process, if the pressure of the air circuit is abnormally increased, it may cause damage to the air pump or even safety accidents. The pressure sensor can monitor the pressure situation in real time. Once the pressure exceeds the safety threshold, it will quickly transmit the signal to the microcontroller. The microcontroller takes immediate measures, such as cutting off the motor power supply, stop inflation, preventing the air pump from being damaged due to excessive pressure, and protecting the safety of the air pump and users.

Provide data feedback and display: The pressure data measured by the pressure sensor can be transmitted to a display module, such as an LED digital tube or an LCD LCD display, allowing users to intuitively understand the current inflation pressure. At the same time, these data can also be transmitted to external devices through communication modules, such as mobile APPs, which facilitates users to remotely monitor the inflatable state and provides users with more convenience and operational flexibility.

Optimize inflation efficiency: By monitoring pressure changes in real time through the pressure sensor, the microcontroller can adjust the operating state of the motor according to different pressure stages. For example, in the early stage of inflation, when the pressure is low, the motor can be run at a higher power and quickly increase the pressure; when the pressure approaches the set value, the motor power is reduced to achieve accurate inflation, which not only improves the inflation efficiency, but also avoids waste of energy caused by excessive inflation and damage to the inflatable object.
