Pressure sensor

This repo is about using Arduino to get te Thin Film Pressure Sensor data. First, you need Arduino IDE/PIO to build the script and upload to the board. Then, using the pySerial to get the data. Finally, you could read and publish data under the ROS platform. This repo as a ros-package.

Sensor Information

Sensor : Film Pressure Sensor Link
