Atmel Interviews Eric on the Gas Sensor for Emergency Workers

Atmel recently published a full one on one interview with Eric from mkme.org on the Gas Sensor for Emergency Workers Atmel states: “Confined spaces can be a dangerous part of rescue work, especially for miners and firemen. Not only do they have to worry about walls caving in and trapping people, but hazardous gasses. And while there are several expensive robotic devices out there that can take gas sensors deep into these tight areas ahead of rescuers, Eric William has…

Arduino DIY Gas Sensor “Grenade” Live on Adafruit ?>

Arduino DIY Gas Sensor “Grenade” Live on Adafruit

Last week I quickly prototyped my Arduino DIY Gas sensor which monitors smoke, LPG (liquefied petroleum gas), and CO (carbon monoxide).  I used the MQ2 smoke/gas sensor and an Arduino nano with a simple ASK 433mhz transmitter to transmit the values out to any radio receiver. It was well received on the Adafruit Show and Tell event as well as Lady Ada mentioned it on the following Ask an Engineer show.  Here are the videos.  Full build video soon with…

MQ2 Smoke, Gas & CO Sensor for Electronics ?>

MQ2 Smoke, Gas & CO Sensor for Electronics

I have been playing with the MQ2 Smoke, LPG, Carbon Monixide gas sensor for Arduino and electronics projects. I have found this little sensor to work quite well as an indicator for gas/smoke levels but the accuracy of the PPM values is a bit questionable. I expect some calibration could improve the accuracy and reliability greatly. I made some quick code which adapts the existing code I found online with my basic Nokia 5110 LCD display code for use with…
