Air Quality Dimensional Sensor Device

Wow, what a name for such a gadget.First of all, what is all that and where does it come from?

I'll try to explain as best as I can what is going on with this project and what purpose it deserves... nope, its main meaning is not only to pass butter.

Tho this gizmo looks kinda funky, it has several useful functions and is not only there to serve an artistic design.

Overall: it's 4 gas sensors, a LCD, a digital thermometer, 2 hall effect sensors and a fully loaded Arduino UNO.

• 5V/3A Step-Down Voltage Regulator
• MQ-5 Gas Sensor
• MQ-135 Gas Sensor
• MQ-2 Gas Sensor
• MQ-7 Gas Sensor
• Hall Effect Sensor Module 2x pack
• Digital Thermometer
• 40 Break Away Header Male
• Arduino Uno
• Rectangle Protoboard 2'' double sided
• 6V 2200mAH NIMH battery pack
• 16x2 LCD Display
• Bicolor LED (2x)
• Wires
• Material for the design
• Plastic casing (7''x 5''x 2.5'' is the minimal size to fit everything)

I won't lie to you, I was highly influenced by the 'Portal Gun' of Rick Sanchez in the great TV show 'Rick and Morty'.

Sadly, this device won't allow me or anyone else to travel through dimensions.Nevertheless, it will gives you a lot of data concerning your environment and the air that you are breathing.

Equipped with 4 gas sensors, 2 hall effect sensors, a digital thermometer and a LCD, the Arduino Uno was loaded in no time.I'm glad I could use nearly all the pin of the micro controller which, in most of the project I've seen, requires so few.

The schematic is currently unavailable but I'm currently working on it.

I really wanted the project to be able to be easily handle by hand.This limited me in the choice of a casing.

I finally went for a 7¨x 5¨x 2.5¨ acrylic plastic casing.

This is the real minimal dimension possible to work with to build such a project.

Trust me. See the video of the main function of the project here:

You will see in this video how everything fits nicely in there:

There is probably 10 versions of the code for this device.

The final one is the right one and the more accurate to what I wanted it to be.

If you are interested, just let me know and I'll try to share all the code with you.
