This is an IoT-enabled Smart Egg Incubator system built with an ESP32 microcontroller, a DHT11 temperature and humidity sensor, a relay-controlled heating element, fan, buzzer, LCD display, and Blynk for real-time monitoring and control.
- Real-time monitoring of temperature and humidity via Blynk mobile app
- Automatic control of heating element and fan based on temperature thresholds
- Visual alerts using LCD display
- Buzzer alert system for abnormal conditions
- Manual relay control from Blynk App
- ESP32 Development Board
- DHT11 Temperature & Humidity Sensor
- Relay Module (for heating element)
- Fan
- Buzzer
- I2C 16x2 LCD Display
- Blynk IoT Mobile App

: Manual relay control
-
Every 5 seconds, the ESP32 reads temperature and humidity values from the DHT11 sensor.
-
The data is displayed on the LCD and sent to the Blynk app.
-
If the temperature:
- Exceeds 38°C → Fan turns ON, heater OFF.
- Falls below 36°C → Fan turns OFF, heater ON.
- Is between 36–38°C → Alert buzzer beeps intermittently.
-
The relay can also be controlled manually via Blynk (V2).
