Pressure measurement device via a wireless network for the seat cushion

This paper presents wireless pressure measuring devices for the seat cushion consisting of an air cushion which reduces the chances of developing a pressure ulcer. A force sensor resistor (FSR sensor) is placed in the position where pressure is most likely to occur. FSR sensor is put under air cushions to help distribute the pressure and reduce the damage which may happen to the sensor. The pressure is applied to the sensors, they will send the data to the microcontroller (Arduino MEGA 2560) and then transmit data via Bluetooth to LabVIEW for display on the monitor screen with the measured pressure range which is divided into different colors. If the pressure is continuously applied for a period of 30 minutes, there will be a notification via the LED light to allow the user to change their sitting positions to reduce the likelihood of pressure ulcers.
