Stress Monitoring System Using IOT

  • Unique Paper ID: 180619
  • PageNo: 2376-2385
  • Abstract:
  • This paper presents a comprehensive IoT based stress monitoring system that integrates environmental and physiological sensing with an Adaptive Neuro-Fuzzy Inference System (ANFIS) algorithm for microcontroller stress is detection. interfaced An ESP32 with a DHT11 temperature–humidity sensor, a photoplethysmography based pulse sensor, and a heart rate sensor to collect real-time data. These multimodal inputs are processed by an ANFIS model to estimate human stress levels. The system features a locally hosted web interface (HTML/CSS) on the ESP32, enabling real-time visualization of sensor readings and the inferred stress status. We evaluate expected performance based on literature benchmarks, anticipating around 90 % classification accuracy, with sensitivity and specificity in the 88–92 % range [2][3][4]. This work contributes a novel integration of ANFIS into IoT-based stress monitoring, demonstrating its potential for enhanced accuracy and adaptability in edge health devices. Future developments will focus on expanding stress level granularity and adding further biosignals.
