When the tire pressure of the car is underpressure, the driving of the car will be affected, and there will be safety hazards. Therefore, if the tire pressure alarm system issues an alarm, it is recommended to replenish the tire pressure in time. Usually, most car owners will have a tire pump in the car in case of emergency.

    At present, the car inflators on the market are divided into two types: pointer and digitally explicit. Among them, the digitally explicit inflated pumps are increasingly accepted by users with their price advantages, ease of operation and other advantages. The main components of the digital explicit air pumps are pressure sensors, which are to monitor the pressure of the air pump when inflating the tires and prevent the tires from passing. High or too low, causing a safety accident.

    Sencoch GZP series pressure sensor, a miniaturized pressure sensor module with high accuracy and wide temperature compensation. Each pressure sensor has been calibrated separately and contains a calibration coefficient, which can compensate for the offset, sensitivity, thermal drift and nonlinearity of the sensor.
