Smoke Detection using MQ-2 Gas Sensor - Arduino Project Hub

06/05/2016· The voltage that the sensor outputs changes accordingly to the smoke/gas level that exists in the atmosphere. The sensor outputs a voltage that is proportional to the concentration of smoke/gas. In other words, the relationship between voltage and gas concentration is the following: The greaterthe gas concentration,the greaterthe output voltage

Carbon Nanotubes as Active Components for Gas Sensors

N 2 absorption characteristics of the vertically aligned CNTs-based three-terminal gas sensor at room temperature were also studied [].Upon exposure to N 2 (filling pressure from 50 mTorr to 500 Torr) and without N 2 at 10 V bias voltage, the electrical resistance of the as-made devices was found to increase and to return back, respectively. Compared to a low bias, a high drain-source voltage enhanced the …
