The purpose of this project is to build a data collection system that can obtain pressure readings in a wind tunnel to determine the speed of the airflow. In this project, data is collected by a pressure sensor and then is interpreted by a microcontroller. This involved building the circuit and programming the microcontroller to receive data from the sensor. We then used an equation that relates the readings from the sensor to a pressure value. When this is complete, we will be able to obtain real time pressure readings from a wind tunnel, which can be used to interpret the impact objects in the wind tunnel have on the airflow. The next step of this project will be to calibrate the sensor with the wind tunnel and determine the baseline airflow profile of the wind tunnel.
