The project consists of developing an electronic system for monitoring the environmental conditions in a baby's room, using the ATMega328P XMINI development board.

• Monitoring temperature and humidity using the DHT11 sensor
• Displaying values on an LCD 1602 screen
• Detecting ambient noise using a microphone module
• Identifying baby crying based on a predefined noise threshold
• Real-time alerting through:
  • buzzer (audio alert)
  • RGB LED (visual alert)

The device uses a DHT11 sensor to continuously measure temperature and air humidity, displaying these values on an LCD 1602 screen to allow monitoring of an optimal microclimate.

At the same time, a microphone module monitors the sound intensity in the room, being programmed to detect the baby's crying when a predefined noise threshold is exceeded.

When crying is detected, the system immediately triggers:

• an audio alert using a buzzer
• a visual notification using an RGB LED

This mechanism provides parents with an efficient real-time alert system.
