PAW_Sensor: This library control the PAW sensor. This library get sensor values from the PAW sensor, and send these values to PC through serial-communication. And you need to convert these values to delta h using some module on PC. I create sample python module for this library. If you want to get this module, please access below page, https://github.com/HiroakiMatsuda/PAW-Sensor The PAW Sensor is developed by RT. If you need to get information about this sensors, please access below page. http://www.rt-shop.jp/index.php?main_page=product_info&cPath=42&products_id=1303
