Abstract:The thesis is part of a bigger project "Plantenna" which is a collaboration of 4 universities. The thesis aims to investigate different types of sensors and designs capable of measuring low airflows (< 1 m/s). The most suitable sensor is designed to measure airflow near the leaf. The challenge is to design a sensor that can measure the airflow without disturbing the crucial parameters like temperature, humidity, and flow itself. The drag force based flow sensor is modelled and simulated in COMSOL Multiphysics 5.5 and verified by an analytical model and finally, fabricated in {MESA}^+ lab at the University of Twente. To characterize the sensor, a test setup is constructed. The velocity profile in the test setup is recorded with Voltcraft's PL-135 anemometer sensor to characterize the fabricated flow sensor.
