This APR10 series differential pressure sensor is dual-signal output precision gas detection module supporting both digital I2C communication and analog voltage signal output, designed for non-corrosive gas differential pressure measurement across smart home, medical equipment, HVAC ventilation, automotive electronics and industrial automation fields. Powered by wide 3.3V~5V standard working voltage, the chip integrates built-in temperature compensation circuit to eliminate ambient temperature drift interference and maintain stable high-precision pressure reading under fluctuating environmental temperature. Adopted compact SOP8 SMD encapsulation with dual vertical air inlet nozzles for convenient pipeline docking and PCB surface mounting, standardized dimension matches universal PCB pad layout to simplify user’s hardware layout design during product development. Two optional output modes flexibly adapt different MCU control schemes: analog voltage output connects directly to system ADC port for quick analog signal collection; digital I2C bus realizes long-distance stable digital data transmission to reduce analog signal loss during wiring. Specially customized for non-corrosive clean gas testing, it reliably captures tiny differential pressure variation of airflow inside ventilator, HVAC pipeline and household air detection equipment to realize real-time airflow monitoring and pipeline leakage inspection. Internal high-stability sensing core resists long-term airflow impact and slight vibration, extending continuous service life for industrial and medical long-running equipment. Wide application coverage includes medical ventilator, household smart air detector, automotive airflow monitoring, industrial wind speed testing and meteorological equipment, becoming universal core sensing accessory for electronic engineers’ prototype development and finished product mass production.
