All Our projectsManage your house with Arduino - Lamps, Heating, Fan, temperature, humidity, etc.
Explanation of the real project and applied in a house
How can you easily make a magic box as big as a hand to manage the whole house with a msartphone, turn on and off the light bulb, the ventialeurs, heaters, know the state of the weather, is it raining? is it cold? know the indoor and outdoor temperature and humidity.
Objects used for this project:
1. mp3 player (WTD020SD or DFPlayer Mini)
2. Distance detector (HC-SR04 sensor)
3. Arduino Mega
4. SD memory card
5. Relay 4 ports
6. Mini Oled Screen 32
7. 2 temperature and humidity detectors module
8. Small speaker
9. Peezo (beeper)
10. Optional: rain detector, Carbon CO detector, sound detector.
