An Efficient FSR-based Approach for Self Notifying Chairs to Minimize Long Duration Sitting Postures

The basic principle of a force sensing resistor is that the resistance decreases with increase in force. This property of the sensor can be used to find its application on many devices and circuits. In this research paper, a FSR is used to find whether a person is sitting on a chair without change in position for too long. The creation of a straightforward tool to track a user’s sitting time and issue a warning if it exceeds a predetermined time limit is described in this proposed work. To save the user the trouble of lugging it, the tool was installed on a chair. As experts say, every 20 minute a person should change his/her posture so as to maintain good health. A circuit is developed in order to acquire the change in signals from the FSR. In order to construct a user-friendly display, LabVIEW software was employed. It is anticipated that the user will be able to spend less time sitting down by using the tool.
