Workers in mines and in other dangerous working areas, are risking their health and life every day!Mining is one of the most dangerous trades in the world. Miners deal every day with dangerous gases and high temperature levels in a dark environment. With the help of Arduino we designed and developed a Smart Working Helmet that can save their lives, if something goes wrong.

The Arduino Smart Helmet is using the Arduino Lilypad board to read values from gas sensor, temperature sensor and light sensor. It has three main abilities:

  • If the worker is approaching to a dangerous gas, the helmet will inform him with a warning sound from the buzzer. If the environment is too noisy, he will know that he is in danger by the red blinking led in the front of the helmet. The warning sound and the red led will repeated faster as he is approaching closer to a dangerous environment.
  • If the environment temperature becomes higher than the worker's body can withstand (e.g. 45 ºC), the helmet will inform him with a (different) warning sound from the buzzer. If the environment is too noisy, he will know that he is in danger from the red blinking led in the front of the helmet.
  • If the working environment becomes darker, the helmet's front light will be turned on.It has a rechargeable battery and can be easily re-programmed to adjust values of the working environment .

(We will post and an presentation video as soon is possible)

Step 1: About License

Smart Working Helmet started out as a Bachelor's thesis by Antonis Damigos and Marianna Miliori at 6/6/2015, (supervised by Michail Papoutsidakis) - Automation Engineering Department of Piraeus University of Applied Sciences.

We are supporting the open hardware - software community so this project will be marked as an open-source. Before share/copy/change anything of below guide, make sure to read and agree with the CC BY-NC-SA licence agreement!

Supporting developer Michalis Vasilakis - Computer Systems Engineering Department of Piraeus University of Applied Sciences.

Read the license info here.

Step 2: What You Will Need - Hardware

  • Arduino board *
  • GAS sensor MQ-2
  • Temp sensor DS18B20
  • Light sensor module (or a photoresistor)
  • Buzzer
  • NPN Transistor (e.g. 2222A)
  • Resistors: 10k, 120, 4.5K
  • Front light (helmet mountable)
  • 3.7 Rechargeable battery
  • Charger controller board

*For Arduino Lilypad (old version) board you may be also need an FTDI to usb converter board.

Step 3: The Circuit

The connections are pretty easy, see the image above with breadboard circuit schematic.

We used the Arduino Lilypad board but you can use also any Arduino board you want, like Arduino UNO, with the same connections.

Step 4: The Code Using Codebender

Here's the code of Smart Working Helmet, embedded using Codebender!

Codebender is an online Arduino IDE - It's the easiest way to program your Arduino board directly from your browser! Just click on the "Run on Arduino" button and that's it! Try it! It's really amazing!


Tip: You can made your own modification in code, just click the "Edit" button.

Step 5: The End

We would like to see photos of your "Smart Working Helmet"!

We hope you liked this, let us know in the comments below!

<p>complete connection photos please !!!!!!!!!</p>
<p>Read step 3 - breadboard circuit schematic!</p>
<p>hello friends, i am doing this project please send the connection photos for smart working helmet as soon as possible </p>
maker after a dream...<br><br>I've been customizing hard hats for a couple of years now, using gaffe tape and foam. just this week, I added mini Maglite leds to one, and a neopixel ring to another.<br><br>the neopixel ring, Gemma, and lipo battery are encased in an empty tape roll on the outside of the helmet, to protect the electronics from the elements and wearer.<br><br>the whole hard hat is deigned to look like a one eyed minion, and my wife wears it to work as a functioning hard hat. The maglite version looks like Kermit the frog, and I wear that one to work.<br><br>smart helms are a brilliant idea, but holes can't be drilled into a hard hat and still have it pass an osha test. some commercial hard hats come with vents predesigned. I wire through those. try that for version 2.0<br><br>
3d print with carbon fiber? I have the idea... but not the funding, or the designs. But designs could be found...
<p>Well , I think that it will be nice. </p>
<p>Hi! Thank you for your comment, yes.. another member told me about OSHA test, I didn't know this. But, this is just a prototype, a first try to have something that will keep workers safe. We can't make a new helmet from the beginning, so we worked on an existing one ;)</p>
Love the idea!<br>a small advice: I know it's just a prototype but you should somehow protect the user from the battery.<br>great work! ;-)
<p>Hi! Thank you for your comment and tip.</p>
I think this is a brilliant idea! The only thing missing(in my opinion) is an MP3. Any plans to try and sell these? I think this could become a standard for safety in the future
<p>Hi! I don't know... maybe in the future ;)</p>
<p>Unfortunately, once you drill a hole in your hard hat, you void the warranty and also make NO longer OSHA acceptable. If they do a safety inspection and look at you helmet with holes in it, they WILL write you and your employer a citation.</p>
<p>Certainly. Nevertheless, this is a proof of concept. Such items can be embedded in new concepts from safety objects manufacturers. I find this very clever and open to other safety points.</p>
<p>Well, this is just a prototype ;) By the way, I didn't know that. Thanks!</p>
<p>Great piece of DIY safety equipment. This could save a lot of lives. </p>
<p>Thank you ! :D</p>
