“…This is related to the Malaysian speed limit between 30 to 110 km/h that has been set as one of the parameters [5]. More details concern is focusing more to the velocity of airflow used in order to increase the performance of airflow sensor, so that, the test of the macrofluidic air flow sensor must be done rapidly to make sure that the accuracy of sensitivity the sensor itself [6]. There are also a few major factors that need to be considered in doing the testing such as humidity, lighting and space to make sure the result is satisfying.…”

This air sensor functioning to detect the speed of air surrounding while in motionor a sudden changes in its environment. The effect of fast detection of a security sensor through the high sensitivity of the airflow sensor has enabled the system to identify and analyze the critical condition in higher accuracy compared to the conventional of any security system. Previous studies have developed the macrofluidic air flow sensor that observed the air flow in higher accuracy while the sensor in motion will be verified by detection of high sensitivity in the relative velocity of the airflow sensor compared to a conventional sensor. An experimental investigation was conducted to verify macrofluidic air flow sensor in wind tunnel by control velocity of range (30 to 110 km/h). The result shows the characterization of the changes in voltage reading with respect to the airflow speed in the wind tunnel. Sensor 1 to 4 have been placed at 0 to 360 degree of orientation with respective of 90 degree space interval.

“…The scope of this study is to focus on evaluating the performance of airflow by determining the little changes of air flow through the airflow sensor based on necessary boundary condition and parameter for low velocity range. Previous papers have shown that usage of Acrylonitrile butadiene styrene (ABS) materials produce different effect towards the performance and detection range for the airflow sensor [1]. The difference in the structure may reflect the performance of the airflow model where some of the sensors use the concept of small insects' detection structure [2].…”

This paper investigates simulation of air flow acting on the airflow sensor using the Computational Fluid Dynamic (CFD) approach. Simulation is carried out to evaluate the performance of airflow sensor by analysing small change of the air flow acting on the airflow sensor structure. Identification of the characteristics and parameters for the sensor in motion was done to achieve higher accuracy of the airflow result. Analyzation stage from the obtained data comprehending the behaviour of the airflow in higher accuracy while sensor in motion will be verified by detection of high sensitivity in relative velocity of the airflow sensor compared to conventional sensor. Therefore, an analysis was conducted with three different airflow directions involving necessary boundary condition and parameter. The efficiency from the tabulated data for dynamic motion has also been determined by comparing simulation data with calculation. All simulations and analyses were completed using the ANSYS software.
