Sitting Posture Correction Device Based on Infrared Distance Measurement

This article designs a posture correction device based on the principle of infrared ranging. A set of distance and corresponding infrared signal data is obtained by the sampling method, and then the data is analyzed to obtain the function of the distance and the output voltage. The infrared module is used to measure the real-time distance from the human head to the desktop, and the distance is used as a reference to remind the sitting posture of the user. The buzzer will be triggered, and an alarm will be generated when the height of user's hand is beyond the set range during use. Unlike traditional mechanical and wearable devices, this device can achieve noncontact measurement, will not restrain human movement or make the body produce physical dependence.
