Practice making DIY- GC 0 124 -Bluetooth APP air purification system
1. Function description:
Design based on STM32 microcontroller- Bluetooth APP air purification system
Features:
Hardware composition: STM32F103C minimum system board + DS18B20 temperature sensor + OLED + SGP carbon dioxide formaldehyde sensor + 5V DC fan + multiple buttons + HC-05 Bluetooth module (only available in Bluetooth version)
1. There are two modes, manual and automatic, and the manual mode is controlled on and off by buttons. In automatic mode, if any value of temperature, carbon dioxide, and formaldehyde is greater than the set value, the fan will be turned on.
2. Gears can be set, 1, 2, and 3 gears are adjustable. 1st gear is the slowest and 3rd gear is the fastest.
3. OLED with multiple buttons can display the set temperature, carbon dioxide, formaldehyde, gear position, switch, manual and automatic, and various states.
4. (Bluetooth version only) HC-05 Bluetooth module module, which can upload temperature, carbon dioxide, formaldehyde, gear, switch, manual and automatic various state settings to the Android APP, and various parameters can be set through the APP. 3. Details:
