Problem:

In healthcare settings, continuous monitoring of patients’ vital signs (heart rate, blood oxygen, temperature, humidity) is critical for early detection of complications. Manual checks are time-consuming, error-prone, and cannot provide real-time data, especially in resource-limited environments.

Benefits to Healthcare:

– Real-Time Monitoring: Immediate alerts for abnormal vitals (e.g., low oxygen, high fever).

– Non-Invasive: Uses sensors like MAX30102 for painless heart rate and oxygen tracking.

– Reduced Workload: Automates data collection, freeing nurses for other tasks.

– Improved Outcomes: Early detection of respiratory distress, hypoxia, or infections.

Solution:

Use ESP32 to integrate MAX30102 (heart rate/blood oxygen), DHT11 (room temperature/humidity), and OLED screens for live data display. Set thresholds to trigger alerts (e.g., buzzer or LED) for critical values.

Process:

1. Sensor Integration:

– MAX30102 captures pulse and oxygen saturation via infrared light absorption.

– DHT11 monitors ambient conditions that may affect patient comfort (e.g., dehydration risks).

2. Data Display:

– OLED screens show real-time vitals (e.g., “HR: 72 bpm”, “SpO2: 98%”).

3. Alert System:

– ESP32 triggers LEDs or buzzers if vitals fall outside safe ranges.

Parts Used:

– ESP32, MAX30102 (x5), DHT11 (x5), OLED Screens (x4), Breadboards (x6).
