MQ4 Methane Sensor Circuit Built with an Arduino

Methane (CH 4) is a colorless, odorless gas with a wide distribution in nature. Methane is known chiefly as being the principal component of natural gas, which is a mixture containing about 75% methane (CH 4), 15% ethane (C 2 H 6), and 5% other hydrocarbons, suh as propane (C 3 H 8) and butane (CH 4 H 10). The principal use of methane is as a fuel. The combustion of methane is highly ...

CH4 (Methane) Gas Sensor Module (27930) CO (Carbon ...

CH4, LPG, and C2H5OH gas sensors where the heater is on or off. To sense CO gas using the CO gas sensor the heater must be driven at 5 V (full power) for the purge phase and V (low power) for the sense phase. The fullpower (purge) phase runs for 60 seconds and the lowpower (sense) phase runs for 90 seconds. These phases cycle continuously as long as the sensor is active. The ALR output ...

Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 01% (010,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
