Description
This is a high-resolution differential pressure breakout with I2C communication, used to measure the difference in pressure across two points on a device.
A high-performance MEMS pressure chip and a special conditioning chip are encapsulated inside the sensor. It will give you a comparative measurement between two points. The sensor IC adopts a unique multi-stage temperature-compensation algorithm to reduce the effect of the environment on the sensor output.
Note: In order to ensure the measurement resolution and the sensor life, please use the sensor in the clean air. Do not let water enter the nozzle of the sensor or it will cause damage.
