Mikroe Air Flow Click contains a flow-based 2-in-1 differential pressure sensor. The board features the First Sensor LHDULTRAM012UB3 LHD ULTRA series micro-flow differential pressure sensor. It’s based on thermal flow measurement of gas through dual micro-flow channels integrated within the silicon sensor chip to effectively maximize the dynamic range of the sensor ranging from 0 to 1250Pa. An on-board MCU with an accurate 24-bit ADC provides signal processing, including response from the two sensing elements, linearization, barometric compensation, and temperature correction.
