Introduction: Crying Baby Monitor With Email Notification

Picture of 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

Picture of 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

Step 3: Code

Picture of Code
#define BLYNK_PRINT Serial
#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"", "Subject: BABY Crying for over 5 minutes", "Your Baby could be in danger or being abused!!!");

void setup()
  // Debug console
  Blynk.begin(blePeripheral, auth);
void loop()

Step 4: App Making
