Hey there. I want to build a smart cabinet.
In my cabinet, I have several consoles and a HTPC/Steam Machine.
I want to equip that cabinet with some TMP36 sensors, a fan and maybe motors.
I am not sure what MCU or makerboard I should use.
Programming in Python, JavaScript, C, C++ are no problem to me.
In the end I will make a custom component for home-assistant, where I can see the temperature of the cabinet.
Here is the logic:
- There are around 2 to 4 tmp36-sensors build into the cabinet. (Inside bottom, Inside top left, Inside top right and one outside)
- Based on the temperature difference, a 4pin fan should be controlled with PWM.
- If the fan is not doing enough of a temperature difference, the cabinet-door should open automatically.
Here is the hardware I currently have:
- 4-5 Arduinos
- 1 Arduino Ethernet-Shield with PoE
- 1 Arduino Yûn with PoE
- 2-3 Raspberry Pi 3B
- ~8 TMP36 sensors
- 12V PSU
- Voltage divider 12V for the fan and 5 for the MCU
- The 4pin fan.
- Cables
- 4 pin male connector for the fan
- Barrel connnector
Things that are unclear:
- There has to be a case, where the MCU/Makerboard is in, including the custom hardware.
- It needs network access. Preferable wired.
