Product description: LWLP5000 I2C Differential Pressure Sensor - DFRobot SEN0343
A high-resolution differential pressure sensor based on the LWLP5000 chip. It communicates via an I2C interface and is used to measure pressure differences at two points within the device. A high-performance MEMS chip and a special conditioning circuit allow for comparative measurements between two points. Furthermore, the system utilizes a unique multi-stage temperature compensation algorithm to reduce the environmental impact on the sensor output. The module allows for pressure measurements in the range of approximately 500 Pa . For proper operation, it requires connection to a microcontroller equipped with an I2C interface, such as an Arduino or Raspberry Pi . It is powered by a voltage ranging from 3.3 V to 5 V.
Main features of the sensor
- Multi-stage temperature compensation algorithm
- I2C digital output
