Mountain Climber Health & GPS Tracker

This guide will help you create a Mountain Climber Health & GPS Tracker to monitor vital signs such as heart rate and oxygen levels, as well as track the climber's location. The system will be designed to provide real-time health and location data, which can be transmitted to a remote server or mobile device for safety and analysis.

Components Required

• Microcontroller (e.g., Arduino Nano, ESP32)
• Heart rate monitor sensor (e.g., MAX30100)
• Oxygen saturation sensor (e.g., MAX30100 or similar)
• GPS module (e.g., NEO-6M)
• Bluetooth or GSM module (for data transmission)
• Battery pack (suitable for the microcontroller and sensors)
• Enclosure (to protect the electronics)
• Connecting wires and mounting materials
• Mobile app or cloud service account (for data monitoring)

Setting Up the Hardware

Follow these steps to set up the hardware:

1. Install Sensors on the Wearable

   Attach the heart rate monitor and oxygen saturation sensors to the wearable device. Ensure the sensors are securely positioned to obtain accurate readings.

2. Integrate the Microcontroller

   Connect the sensors and GPS module to the microcontroller. Properly wire each sensor to ensure reliable data acquisition.

3. Install the Communication Module

   Attach the Bluetooth or GSM module to the microcontroller for data transmission. Configure the module to communicate with your mobile app or cloud service.

4. Power the System

   Ensure that the power supply is sufficient for both the microcontroller and sensors. Use a battery pack that provides adequate power for the duration of the climbing expedition.

Programming the Microcontroller

Write code for the microcontroller to read sensor data, transmit it to the mobile app or cloud service, and optionally manage the GPS module. Here’s a basic outline of the code:

                #include <Wire.h>
                #include <Adafruit_Sensor.h>
                #include <Adafruit_MAX30100.h>
                #include <TinyGPS++.h>
                #include <SoftwareSerial.h>

                Adafruit_MAX30100 max30100;
                TinyGPSPlus gps;
                SoftwareSerial gpsSerial(4, 3); // RX, TX for GPS
                SoftwareSerial btSerial(10, 11); // RX, TX for Bluetooth

                void setup() {
                Serial.begin(9600);
                gpsSerial.begin(9600);
                btSerial.begin(9600);

                max30100.begin();
                }

                void loop() {
                // Read health data
                float heartRate = max30100.getHeartRate();
                float oxygenLevel = max30100.getOxygenSaturation();

                // Read GPS data
                while (gpsSerial.available()) {
                    gps.encode(gpsSerial.read());
                    if (gps.location.isUpdated()) {
                    float latitude = gps.location.lat();
                    float longitude = gps.location.lng();
                    
                    // Format data for transmission
                    String data = String("HR=") + heartRate + "&O2=" + oxygenLevel +
                                    "&Lat=" + latitude + "&Lng=" + longitude;
                                    
                    // Send data via Bluetooth
                    btSerial.println(data);
                    }
                }

                delay(10000); // Wait 10 seconds before next reading
                }
            

This code initializes the sensors and GPS module, reads data, and sends it via Bluetooth. Adjust the code to match your specific sensors and communication module.

Setting Up Data Monitoring

Configure your mobile app or cloud service to receive and display the data. Ensure that the app or service can handle the incoming data and provide real-time feedback on the climber's health and location.

Testing and Calibration

Before deploying the tracker:

1. Test the Sensors

   Ensure that the heart rate and oxygen saturation sensors are functioning correctly and providing accurate readings. Verify that the GPS module is obtaining location data.

2. Calibrate the Sensors

   Calibrate the sensors as needed to ensure accuracy. Follow the manufacturer's calibration guidelines.

3. Check Data Transmission

   Verify that the data is being transmitted correctly to the mobile app or cloud service. Ensure that the communication module is working as expected.
