Smart IoT Controller
This project is made to handle home IoT and it can also be used for training.
This board has several features :
- 220 VAC to 12 VDC
- 3 Relays
- complete pin header I / O
- has a 12V, 5V, 3.3V voltage Option
- Support Buzzer
- Ready Connect with Any Raspberry
- Components can be found easily in a grocery store
- Easy application
- Easy Coding and Development
Weakness :
- cannot be placed outdoors
- there is no packaging to cover it
Schematic can be downloaded here : https://drive.google.com/file/d/1SQlmgDix5kAZFoeRvaRsisJBKdYHPbxM/view?usp=sharing
Nodemcu and Raspberry Connected with Pins:
Nodemcu : D1 and D2 (I2C)
Raspberry Pi Pico : GPIO 26 And GPIO 27 (SDA & SCL)
With this board, it is hoped that it can develop IoT projects without complicated cable wiring and advanced development. Raspberry Pico can be used as an offline controller if there is no internet connection connected nodemcu. communication between raspberry pico and nodemcu will later be connected to the I2C / UART port that I have prepared on the Smart IoT Controller and if nodemcu is already connected to raspberry then nodemcu will only be the sender to the existing database / server. and the main control will be taken over by the Raspberry Pi. So sorry if there is no raspberry pico. because in Indonesia itself the item is still not available. but the project that I made is ready to be linked with any Raspberry and if controller
