NADI PARIKSHA AS A STRESS INDICATOR IN AN ARDUINO-BASED WIFI SIGNAL STRENGTH MEASURING DEVICE

Abstract
WiFi has been introduced practically everywhere in our lives, from home to school to university. Although there is research on the health impact of WiFi signals on living creatures, public awareness of these effects remains limited. Although there are numerous smart devices to measure stress levels, they rely on complex mathematical computations performed in the frequency domain. On the other hand, the Nadi Pariksha method—an ancient Indian diagnostic technique—relies solely on pulse measurements taken at three neighboring points on the arm, near the base of the thumb. We have encountered its potential for use in stress measurement. For this purpose, we designed and realized an ESP12E-based system to measure WiFi signal strength and an Arduino Uno-based system to measure Nadi Pariksha pulses. Our results, compared to the output of a commercial smartwatch used as a stress indicator, show a stress-correlated amplitude increase in the Pita signal within 1–3 meters of a WiFi router. This work demonstrates the prominent potential of Nadi Pariksha in evaluating stress induced by WiFi signals.
