This paper describes the development of a simple tool to record the sitting time of a user, and give a warning if his/her sitting time exceeds the specified time limit. The tool was mounted on a chair to make the user free from the hassle of carrying it. The tool was made using a Seeeduino Stalker, which is a microcontroller board for wireless sensor network, with data logger functionality. The tool was equipped with a pressure sensor, FSR, to determine whether the chair is occupied, and a Buzzer to provide a warning sign. LabVIEW software is used here to create a user-friendly display. By using the tool, it is expected that the user can reduce his/her sitting time. |
