Smart Iot Device for Weather And Health

This project shows an IoT Weather and Health Monitoring System based on the Raspberry Pi Pico W to monitor essential health parameters and environmental factors in real-time. It includes a BME280 sensor for temperature, humidity, and pressure, an MQ135 sensor for monitoring air quality, a Ds18b20 body temperature sensor, and a MAX30100 pulse oximeter and heart rate sensor for heart rate, SpO₂ level, and body temperature measurements. An OLED screen offers in-device feedback, and IoT connectivity along with a GSM module offers remote monitoring and real-time SMS alerting for emergency alerts like high fever, low air quality, dehydration hazard, and altitude-related oxygen shortage. The MQ135 sensor offers more environmental sensitivity through pollutant detection, which makes the system very useful for users in environments with low air quality. The GSM module guarantees alerts are sent even in areas with poor internet connectivity. The intelligent IoT prototype is suitable for outdoor enthusiasts, the elderly, and patients with respiratory or cardiovascular diseases, providing real-time monitoring of health, environment, and emergency alerts. Future upgrades could involve AI-powered predictive analytics, integration with mobile health apps, and cloud data logging for long-term trend identification and enhanced emergency response.
