DFRobot SEN0343 Differential Pressure Sensor Module is a high-resolution sensor with I2C communication is used to measure the difference in pressure across two points on a device. This pressure sensor module is encapsulated with a high-performance MEMS pressure chip and a special conditioning chip inside the sensor. The SEN0343 sensor module adopts a unique multi-stage temperature-compensation algorithm to reduce the effect of the environment on the sensor output. This differential pressure sensor module features a multi-stage temperature-compensation algorithm. Applications include home medical care equipment, portable medical equipment, medical monitoring, industrial control, and a central ventilation system.
