Introduction: Fall Detector With Email Notification of GPS Coordinates

Picture of Fall Detector With Email Notification of GPS Coordinates

The average age of our population grows, yet people are also getting busier and busier with never enough time to take care of every one dear to our heart. Make this simple and small fall detector that sends an email notification of their GPSCoordinates via a Bluetooth Connection to a Smartphone. to you whenever it senses extreme motions, so that you can be there to respond as soon as possible.

Protect your loved ones! Build this arduino fall detector today!

Step 1: BoM

Picture of BoM


  • Arduino 101 board
  • something to attach the board to a person (e.g. a strand of string)
  • a battery pack

Additionally, you'll need:

  • Arduino IDE
  • FunguyPro Server

Step 2: Wrap

  • Assemble the power unit with the board using the string
  • connect the power unit to the power input of the arduino board

Step 3: Code

Picture of Code
#define BLYNK_PRINT Serial<br>/* Set this to a bigger number, to enable sending longer messages */
#include "WiFi.h"
#include "WiFiClient.h"
#include "BlynkSimpleEsp32.h" // replace"" with <>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "YourNetworkName";
char pass[] = "YourPassword";
void emailOnButtonPress()
  CurieIMU.setDetectionThreshold(CURIE_IMU_SHOCK, 1500); // 1.5g = 1500 mg
  CurieIMU.setDetectionDuration(CURIE_IMU_SHOCK, 50);   // 50ms
if (CurieIMU.getInterruptStatus(CURIE_IMU_SHOCK))  {
    GpsParam gps(param);"Subject: URGENT EMERGENCY Fall has been detected! GPS Coordinates: %d latitude, %d longitude", gps.getLat(), gps.getLon);
   tone (5, 10000);
void setup()
  // Debug console
  Blynk.begin(auth, ssid, pass);    // get this from your phone
void loop()

Step 4: App

Picture of App
  • Make a bluetooth (BLE) widget to interface the Arduino board
  • Make a web request widget to communicate with your email server

Step 5: Deploy!
