Product description: LWLP5000 I2C Differential Pressure Sensor - DFRobot SEN0343
High resolution differential pressure sensor based on theLWLP5000chip. Communicates viaI2Cinterface, used to measure differential pressure at two points on the device. High-performanceMEMSchip and a special conditioning circuit, allows to make comparative measurements between two points. In addition, the chip uses 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 approx.500 pa. It requires connection to a microcontroller equipped with an I2C interface, such as anArduinoorRaspberry Pi, to work properly. It is poweredfrom 3.3V to 5V.
Main features
