Mikroe Air Flow Click: Affordable, Precise Pressure Sensor Board for Medical & Industrial Use

MikroElektronika has unveiled the Air Flow Click, a compact air‑flow monitoring peripheral designed for applications that demand high precision, an extended measurement range, and the simplicity of a single, ready‑to‑use device. Priced at just US$25, the board is well suited for sensitive medical equipment such as ventilators, spirometers, and sleep‑diagnostic systems, as well as precision industrial tasks like leak detection.

At its core is a flow‑based 2‑in‑1 differential pressure sensor from First Sensor (a TE Connectivity brand). The LHDULTRAM012UB3, part of the LHD ULTRA series, measures thermal flow through dual micro‑flow channels embedded in the sensor chip, enabling a dynamic range of 0 to 1 250 Pa. An on‑board microcontroller with a 24‑bit ADC processes the raw signals, providing linearisation, barometric compensation, and temperature correction.

“We’re all under pressure these days, but for just $25 USD designers can purchase Air Flow Click, a fully tested product ready to integrate into their system,” said Nebojsa Matic, CEO of Mikroe.

The Air Flow Click ships with a mikroSDK‑compliant library that includes high‑level functions to accelerate software development. Its 16‑pin mikroBUS socket—an industry standard invented by Mikroe a decade ago—offers a consistent interface: three communication buses (SPI, UART, I2C), six ancillary signals (PWM, interrupt, analog input, reset, and chip select), and two power rails (+3.3 V and +5 V).

Click boards simplify the design process, allowing engineers to swap peripherals in a matter of minutes and eliminating months of development time. Mikroe releases a new Click board nearly every day at 10 a.m.; Air Flow Click is now part of a growing family of 32 pressure‑sensor Clicks that cover a broad spectrum of use cases.

Microchip was among the first major chipmakers to adopt the mikroBUS standard in 2016, and all current Microchip development boards feature at least one mikroBUS socket. The standard is also supported by leading microcontrollers from Renesas and Toshiba on their development boards.

With its combination of affordability, proven accuracy, and seamless integration, the Air Flow Click offers a reliable solution for precision airflow measurement across medical and industrial sectors.
