Vacuum Pump V2 (DC motor pump)
Electronic board to automate the vacuum pump
This board has the following characteristics:
- An ESP32 microcontroller will handle all the logic and communication with smartphone over Bluetooth Low Energy and WIFI over UDP
- two 5V relay boards can handle a 230V AC fridge motor coils (compatibilty with fridge compressor)
- an OLED display could be used for debugging
- a pressure sensor will convert vacuum level into a voltage read by the ADC of the MCU
- a DC motor can be controlled via N channels Mosfets
- a brushless DC motor can be controlled with an ESC controller (optionnal 5V control stage)
- The board is powered (optionnaly) with a cheap 12V to 5V DC/DC converter
So this board should be more versatile than the previous one!
A devoted Hackaday's project has been created. Please follow this project for more details : DC motor Vacuum pump @Hackaday
It demonstrates how to control this 12V DC motor pump :
Here is the video of the PCB soldered
And finally here is the system fully working:
