IOT BASED SMART Cradle for Baby monitoring Electronics engineering final year project

IOT module (ESP8266) interfaced with Arduino UART port. DHT11, MIC sensor, MEMS sensor, Moisture sensor and servo motor interfaced with Arduino digital pins.

WORKING:

Arduino is main heart of this project and it will read all sensors and control cradle swinging. When Baby cries then MIC sensor identify and gives signal to Arduino. Arduino send PWM pulses to servo motor to swing cradle. MEMS sensors attached to baby to monitor moments of baby. When baby moves fan will be ON. If baby urinates then buzzer will be ON. Arduino reads all sensors data and displaying on LCD. Also, it sends sensors data to IOT cloud server through ESP8266. We can monitor baby conditions when baby is in cradle from remote server.
