Single chip microcomputer STM32L151CCU6

Photocoupler

[Application] Absolute pressure integrated sensor

The MPX4250 is an absolute pressure integrated sensor. It is mainly used in the automobile engine control system. It can measure the absolute pressure of the engine intake pipe, and then calculate the fuel required by each cylinder through the computer juice to ensure the engine is in the best working condition.

On the integrated sensor chip, in addition to the piezoresistive pressure sensor, there is a signal igniter and a thin film resistor network for temperature compensation. The film network can be calibrated using laser technology. The pressure measuring range is 20~250kPa, and the corresponding output voltage is 0.2v~4.9V (can be directly interfaced with the single-chip microcomputer with A/D converter), and the working temperature range is -40°C～+125°C.
