A distiller controller


I would like to make an alcohol distillation column controller with the option of reading data from the phone. Controller functions:

- temperature reading from 4 DS18B20 sensors.

- support for 4 motor valves (CWX-25 CR-05 12V) - adjustable every 5 percent

- support for 9 kW / 400V heater (three phases) - adjustable every 2.5 percent

- wi-fi & bluetooth support

To start with, I only need the temperature reading and the ability to change parameters (opening of the motor valves, heater power) in the android application. Without any algorithms or settings.

The application must be as simple as possible: buttons to control the power of the heaters and to control the opening of the valves, temperature reading, start / stop button, bluetooth connection status. Picture is in files.

I need PCB designs, schematics and source codes so that I can do it myself.

For now, I would like to ask about the vision of this driver, the estimated cost and time of implementation.

After some time I will need to supplement the equipment with algorithms, the ability to change settings etc.

I'd like to use:

ESP32-S WiFi + bluetooth
