Baby Monitor

BabyMonitor, is a prototype of a sensor that detects when the baby is crying, and automatically alerts the parents via a phone call, and starts playing lullaby with a simple light touch to soothe the baby.

The current version is a working prototype, which showcases the main ideas. The main design goal is not re-inventing Baby Monitor, but to illustrate how to build the sensor using Arduino.

Project Layout

• /Docs contains the Arduino circuit diagram and the final prototype.
• /babyMonitor contains the Arduino sketch.

Required Materials

• Arduino UNO
• Breadboard
• Jumper Wires
• Sound Detector
• Arduino GSM Shield
• Piezo Buzzer
• 2x LED
• 2x 560Ω Resistor
• Box or children's toy

Connecting the components

• Attach the GSM Shield to Arduino UNO.
• Connect the Sound Detector red cable (+) in Arduino digital pin #5 and black cable (-) into ground pin.
• Connect the Piezo Buzzer red cable (+) in Arduino digital pin #8 and black cable (-) into ground pin.
• Connect the Sound Detector (+) in Arduino digital 3.5V and black cable (-) into ground pin, and Pin A0 to pin #5.
• Connect and Set the LEDs in pin #12 and #11 to light-up.
• "Twinkle Twinkle Little Star" is the melody that have been used in this project, you can costumize your own melody by going through this tutorial.
• Put the sensor inside a box or a children's toy.
