Amazing Home automation system with STM32F103 microcontroller Part 1

Amazing Home automation system with STM32F103 microcontroller

Visit my Youtube channnels :  Electro_Magic ; Practical Tips  ; Delphi practical school             

This is ongoing project of building Home automation system ( smart home system ), which will for the start have measurement of temperature and humidity.

It will consist of number of parts ( number of blog posts ).

It is planed to work with micro controller STM32F103C8T6

 and 3.5" TFT LCD.

Next step will be to control relays for ceiling fan, etc.

Next will be to add ESP8266 to have connection to the internet, so the system can be controlled remotely.

Till now I have managed to make a printed circuit board.

Not really nice to look at, but it is working, and working from the first attempt :-)

The PCB is designed in EasyEDA, and made with toner transfer method 

Except headers for STM32 and TFT LCD, I have also added 3.3V and 5.0V linear regulators.

Beside this, there is also part with MC34063 as a buck converter, which is in front of small linear regulators.

This part is made with intention to connect this device to external power source of 12V.

Of course, everything is programmed using Arduino IDE and STM32duino board.

For measuring temperature and humidity we use DHT11 sensor, which measures temperature and also humidity and uses just three wires, plus, ground and signal.
