VAV Press Click is a compact add-on board that contains a board-mount pressure sensor. This board features the LMIS025B, a low differential pressure sensor from First Sensor (part of TE Connectivity). It is based on thermal flow measurement of gas through a micro-flow channel integrated within the sensor chip. The innovative LMI technology features superior sensitivity, especially for ultra-low pressures ranging from 0 to 25Pa. The extremely low gas flow through the sensor ensures high immunity to dust contamination, humidity, and long tubing compared to other flow-based pressure sensors. This Click board™ is suitable for pressure measurements in Variable Air Volume (VAV) building ventilation systems, industrial and respiratory applications in medical.

VAV Press Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

CO 2 click is a very accurate, carbon-monoxide-gas-sensor Click board™, equipped with the SPEC amperometric, 3SP CO 1000 gas sensor which electrochemically reacts with the carbon monoxide (CO). It is supported by the LMP91000, a high-precision integrated analog front-end IC (AFE), perfectly suited for use in electrochemical, sensing applications. The Click board™ also provides the reference voltage required by the sensor and it offers a choice between the analog output from the AFE IC buffered with the low noise op-amp, and the digital output from the 12-bit SAR A/D converter.
