Product Description

Single-chip based solution:

1) Single differential pressure sensor for suction detection

2) One side of the device diaphragm is in contact with the airflow channel, and the other side is in contact with atmospheric pressure; waterproof and oil-proof

3) Multiple output interfaces: interrupt, frequency, I2C

Product Advantages:

1) Low cost: single-chip differential pressure detection, more compact overall design

2) Oil resistance: adopts back-pressure intake method, waterproof and oil-proof

3) Consistency: MEMS micron-level processing technology, small device differences, and factory pre-calibration testing to ensure consistent trigger pressure
