The The MikroElektronika's Air Flow Click is a compact add-on board that contains a flow-based 2-in-1 differential pressure sensor. This board features the LHDULTRAM012UB3, LHD ULTRA series micro flow differential pressure sensor from First Sensor part of TE Connectivity. This pressure sensor is 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. This Click board is ideal for air flow monitoring and medical applications that demand high precision, extended measurement range, and the convenience of a single device.
