This project is an aproach to understand how neonate incubator works. !!WARNING!! IT IS NOT SUPOUSED TO TAKE CARE OF ANY KIND OF LIFE, the purpose here is to understand the basics and get your project as better as possible, and of course have fun with it!!
This was made to represent the idea of low cost medical devices for a diploma work.
The main goal of this incubator is to mantain the temperature between a max and min temperature range, this temperature range can be managed with a 5-button control. The airflow is created with help of two fans that keep air flowing (two fans works at small velocity but one of them has an increased velocity switch in case of overwarming airflow), a ceramic warmer, a servo motor to open and close a gate that lets overwarmed air to flow outside the system, temperature and humidity sensors, a power supply and of course, our good Arduino Nano.
An upside view of the system
Here is the ceramic warmer, some sensors and the servo controlled gate
Here you can see the place in which the air is warmed, a Lm35 temperature sensor is in the top of the box
This project will be divided in several small projects in order to explain how to build each specific part that need special attention as the power controller and the button controller.
Simplified diagram
This diagram content the following:
1. 220V cable
2. Power source 220v to 24V @ 4A
3. Arduino Nano
4. I2C 20x4 LCD
5. Power controller for fans and warmer
6. 5-button control
7. Ceramic warmer
8. Lm 35 temperature sensor
9. DHT22 humidity and temperature sensor
10. 12V computer fan
11. Small servo motor.
12. Big plastic box
1. 220V cable

3. Arduino Nano
4. I2C 20x4 LCD
5. Power controller for fans and warmer
6. 5-button control
7. Ceramic warmer
8. Lm 35 temperature sensor
9. DHT22 humidity and temperature sensor
10. 12V computer fan
11. Small servo motor.
12. Big plastic box
Power management
The two independent lines were made experimentally to check if the helped to avoid some noises, but they did not :) So you can use just one.
Amplification stages and voltage follower
Voltage follower is used to have better signal from thermistors and the OpAmps to expand the Lm35 readable range in Arduino
Code for Arduino Nano
C/C++I am very sorry that this code lacks documentation but as soon as possible I will upload and upgrade to it, so you can edit it easily.
