Abstract
The quality of human life is an important aspect that must be considered. Sitting is one of the activities humans routinely carry out, which causes several health risks if not done correctly for a long time. Several studies have been conducted regarding the upper limb sitting position, but little has been discussed about the lower limb. Therefore, this paper presents the Autonomous Height Adjustment System (AHAS) for Internet of Things (IoT)-based Smart Office Chairs. This study focuses on adjusting the height of office chairs based on the user's body weight. Modifications need to be made to standard office chairs by adding load cell sensors and linear motors as actuators. The main unit microcontroller reads data from sensors and actuator controllers based on the proposed algorithm. The data obtained is then stored on a cloud server using the IoT concept with the HTTP protocol to monitor it in real-time. Several phases were carried out, from the mechanical, electrical, and software design stages, subject selection, and data acquisition to the implementation stage. The results presented show that the proposed system can work well and be a solution for autonomous seat height adjustment. A low-cost IoT-based prototype Autonomous Height Adjustment System for smart office chairs has been successfully developed and presented in this paper.
