Automated environmental alert system

DJ‘s Instructable describes an automated environmental alert system consists of four gas sensors to meausure the concentration of methane, propane, carbon monoxide, and smoke in the air and are connected to an Intel Edison for wireless detection and alerting. The entire system runs with a 5V 3A power supply and the sensor data are read through 4-analog input channels of the Intel Edison board. He used an Arduino breakout board for Intel Edison for rapid prototyping of his project.

An Intel Edison runs the show for the Environmental Alert System. The Edison is mounted on an Arduino breakout board, which makes it easy to read the analog signals from the sensors and potentiometers. The Edison is connected to the 5V rail via a micro usb cable. The Edison has a built-in Wi-Fi radio, which allows it to connect to the internet without the need for any additional hardware. 

The system has four sensors that connect the Edison. Each sensor is directly powered from the 5V rail and has its signal pin connected respectively to A0 through A3 on the Edison breakout board. The sensors also each have a sensitivity adjustment resistor; the MQ-7 has a 10K ohm resistor and the rest each have a 20K resistor. The MQ-2 is a combustible gas sensor (liquified petroleum gas, propane, hydrogen, and methane) that outputs an analog voltage proportional to the concentration from 300 to 10,000 parts per million. The MQ-4 is a methane gas sensor and has a equivalent concentration to voltage response. The MQ-6 is an LPG, isobutane, propane sensor. The MQ-7 is a carbon-monoxide sensor.

Portable password keeper using Intel Edison

Daniel Gilbert shares his experience of building the PinTin Nano, a Intel Edison powered portable password keeper.

PinTin Nano stores passwords for your accounts

With this instructable, I try to solve a problem everyone has: Passwords. Accounts. Logins. All the stuff you need to get into your favourite social media site, shopping site, blog or forum (they still exist, huh?). Now, there are several ways to control your accounts:

  • Use always the same credentials: No. Never ever do that. Seriously. If your account gets hacked on one site, chance is that the hacker(s) will try the credentials on other, popular sites also. Don’t underestimate them. They are smart. Criminals, but smart.
  • Use a software on every device: You can do that. And if you are lucky, this software will run forever on this device. But maybe, at some point, you will get rid of the devices. Uh-oh…
  • Write them down: Yepp. You can do that. But – everyone who finds your book will be able to read your passwords. That wouldn’t be that great, right?

To solve all of this, I created a device called “The PinTin Nano”. It has it’s name from the fact that it’s a) pretty small and b) fits in a mint tin. I love that, because that makes the device easy to carry around.
