Sensirion Mass Flow Sensor Arduino library, modified from MyElectrons and Nabilphysics Arduino repositories for SFM3300 Digital Mass Flow Sensor. When the sensor data gets stuck, the library has a hard reset function to ensure that it is read continuously.

Using the concepts of water seals and pressure operated devices we have designed and built an affordable, scalable and reliable positive-pressure ventilator.
