Arduino DIY Gas Sensor "Grenade" Live on Adafruit - MKME Blog

02/03/2015· Arduino DIY Gas Sensor “Grenade” Live on Adafruit. Spread the love. 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. Arduino Gas Sensor. It was well received …
