Crying Baby Monitor With Email Notification

Maybe you're leaving you're baby at the hands of a nanny or even the day care and being a concerned parent you want to gauge whether he or she is being treated well. This alarm notes the high peaks when a baby is crying and when it passes a certain threshold alerts the user.

I made this project in the hopes of preventing abuse for both children's and toddlers alike and hope that it will make a difference in parent's lives!

Step 1: BoM

* Arduino 101 (because it has a real time clock and Bluetooth low energy)

* Alternatively, Arduino Uno + RTC + Bluetooth module

* Sound Detector Board

* Bluetooth Low energy-capable phone

Step 2: Wiring

I/O	I/O Pin #	Wire Colour	Arduino pin#
Sound Detector Board	VCC	Orange	VCC
GND	White	GND
Envelope	Yellow	A0

Step 3: Code

#define BLYNK_PRINT Serial

#define BLYNK_MAX_SENDBYTES 128

#include <BlynkSimpleCurieBLE.h><blynksimplecurieble.h>
#include <CurieBLE.h</blynksimplecurieble.h>>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "795aa10d38cf4a4c987de4be9b6d0de3";
int counter - 0
BLEPeripheral  blePeripheral;

void emailOnButtonPress()
{
  // *** WARNING: You are limited to send ONLY ONE E-MAIL PER 15 SECONDS! ***

  // Let's send an e-mail  given the following conditions
  
  if (analogRead(A0)>300) {
    long logTime = time();
  }
  if (analogRead(A1)>300 && (time() - logTime() > 300){
    counter +=1;
    Serial.println("Dog / Baby is Overheating in the Car!!!"); // This can be seen in the Serial Monitor
    Blynk.email("[e-mail]", "Subject: BABY Crying for over 5 minutes", "Your Baby could be in danger or being abused!!!");

  }
}

void setup()
{
  // Debug console
  Serial.begin(9600);

  delay(1000);

  blePeripheral.setLocalName("TechMartian");
  blePeripheral.setDeviceName("TechMartian");
  blePeripheral.setAppearance(384);

  Blynk.begin(blePeripheral, auth);

  blePeripheral.begin();
}

void loop()
{
  blePeripheral.poll();
  Blynk.run();
}

Step 4: App Making

Follow the images above on how to setup your own application.

* Grab the following widgets:

1. BLE
2. Email
3. Notification

* Connect to your device.

* Add your email address

* Click Run

That's it, you're done. Enjoy!
