An IoT-based Sitting Position Monitoring and Alert System

Maintaining a healthy sitting position is critical for preventing musculoskeletal disorders including back discomfort and neck strain, especially in people who spend long periods of time sitting or working in front of computers. This study describes an IoT-based sitting position monitoring and alarm system that detects incorrect sitting positions by combining flex sensors and accelerometers. The technology uses a flex sensor to monitor spinal cord bending and an accelerometer to determine angle of neck movement. A microcontroller processes data from both sensors and decides whether the user is sitting correctly or incorrectly. In the event of a poor seating position, an incorporated buzzer informs the user, requiring fast rectification. The device also features cloud connectivity to save seating position data, allowing for remote monitoring. This tool enables healthcare providers to generate reports and track users' seating behaviours over time, giving significant data for sitting position-related healthcare interventions. The suggested system provides an effective solution for real-time sitting posture monitoring, with the goal of preventing sitting-related health disorders and improving general well-being.
