Pressure sensor device and chair system having the same

Abstract

A pressure sensor device includes: a first air pack which contains air therein; a pressure sensor which is disposed in the first air pack to measure air pressure inside the first air pack; a second air pack which contains air therein; and a hose connected to the first air pack and the second air pack so as to allow air to communicate therebetween, wherein the air pressure sensor measures an air pressure change inside the first air pack which is generated by a pressure applied to the second air pack, and the pressure sensor device measures the pressure based on the air pressure value measured by the air pressure sensor. A chair system includes the pressure sensor device, and a pressure is measured based on the air pressure value measured by the air pressure sensor of the pressure sensor device.
