Make a Simple Ventilator - 2nd Part, the Ventilator CPU
1065 0 Jul 13.2020, 14:42:02

This is the 2nd part of the Simple Ventilator System (SMS), it's basically based on an Arduino development board/kit,
there are 3 options of Ventilator CPU board:

1. Based on Arduino Uno board, whereas this well known ready made board is available (almost) everywhere so   

  this Simple Ventilator System hopefully can be made anywhere & everywhere in answering today

  requirement of people respiratory machine

2. Based on Arduino Mega by ATmega 1280/2560 micro controller, herewith we modify this board as

  described on the enclosed picture with addition on:

    - WiFi connection option by using WeMos D1 Pro Mini or Omega 2 module
    - 3 analog interfaces for analog sensor/push button switch
    - I2C interface for LCD module
    - I2C ports for pressure/temperature sensor connection 
    - 2 ports for small DC motor control
   by those addition, this board become fully Medical Internet of Things with 2 option of WiFi connection,

   incorporate with I2C for sensors & display for Human Machine Interface, some ports available for sensor(s) connections & 2 DC motor controller.

3. Based on STM32F103 Blue Pill board, which is under development, the capability is as point 2 above with addition for:

   - I2C EEPROM storage memory about 32 or 64 kbit capacity for machine configuration

   - I2C Real Time clock for data time stamping

   - micro SD/TF card for memorizing patient condition data

   - on board port connection available for optional module of Serial LCD or I2C LCD module

   - some pins are open for connection of module(s) with can be gated/controlled
   - Serial Communication port for programming the STM32 module (optional can be STM32F303, etc).
