The sensitivity of two commercial metal oxide (MOx) sensors to ethylene is tested at different relative humidities. One sensor (MiCS-5914) is based on tungsten oxide, the other (MQ-3) on tin oxide. Both sensors were found to be sensitive to ethylene concentrations down to 10 ppm. Both sensors have significant response times; however, the tungsten sensor is the faster one.

It has two inbuilt LEDs power LED and a digital output indication LED. The pinout of the MQ-4 Methane Gas Sensor module is as shown:
MQ Gas Sensor Series. MQ gas sensor series are the most common gas sensors available. These sensors have various models for detecting various gases, some of which are listed in the following table: Here we will get to know how to hookup MQ9, but they all work almost in the same way.
Oct 07, 2018· MQ-3 Equivalent Sensors. MQ-2, MQ214 (detection of Methane), MQ303A . Brief Detail about MQ-3 Gas Sensor. MQ-3 module is suitable for detecting Alcohol, Benzine, CH 4, Hexane, LPG, material of MQ-3 gas sensor is SnO 2, which with lower conductivity in clean the target alcohol gas exist, the sensor’s conductivity is more higher along with the gas concentration rising.
Jun 05, 2019· The MQ-2 smoke sensor is sensitive to smoke and also responsive to the following flammable gases: LPG. Butane. Propane. Methane. Alcohol. Hydrogen. The resistance of MQ2 varies depending on the type of gas. The smoke sensor has a built-in potentiometer that adjusts the sensitivity of the sensor based on the accuracy of the gas you are testing.
The 8-sensor array consists of two boards: 1 PCB with just 8 gas sensor sockets and a separate board with a dedicated power connection, potentiometers for each sensor and headers for plugging in an Arduino nano. It's pretty perfect. No wiring or soldering to be done, and you just need to write an Arduino sketch to read A0-A7 at your desired ...
Electrochemical Ethylene Gas Sensor ME3-C2H4. Winsen Electronics, professional gas sensing solution provider, produces ethylene gas sensor, C2H4 sensor for industrial and fruit ripening use. ME3-C2H4 electrochemical gas sensor make use of electrochemical oxidation process on the working electrode in electrolytic cell.
Feb 16, 2018· Features of the MQ sensors. Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage ...
MQ-3 Sensor. MQ-3 alcohol sensor can be used to detect vapor of alcohols such methanol and ethanol. It means, MQ-3 sensor is so much sensitive for alcohols. But less sensitive to benzene. MQ-3 sensor is a cheap sensor and you can buy it from online sellers.
Jan 04, 2018· MQ2 Equivalent sensors: MQ-6, AQ-2, MQ-306A, AQ-3 . Selecting between Sensor type and module type. When it comes to measuring or detecting a particular Gas the MQ series Gas sensors are the most commonly used ones. These sensors can either be purchased as a module or as just the sensor …
MQ-4 Semiconductor Sensor for Natural Gas Sensitive material of MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising.

Jan 18, 2020· The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. They can be calibrated more or less (see the section about “Load-resistor” and “Burn-in”) but a know concentration of the measured gas or gasses is needed for that.
Give your next Arduino project a nose for gasses with the MQ2 Gas Sensor Module. This is a robust Gas sensor suitable for sensing LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations in the you are planning on creating an indoor air quality monitoring system; breath checker or early fire detection system, MQ2 Gas Sensor Module is a great choice.
Mar 18, 2020· The sensor responds to ethylene within a few seconds of exposure, and once the gas is gone, the sensor returns to its baseline conductivity within a few minutes. “You’re toggling between two different states of the metal, and once ethylene is no …
The MQ-2 smoke sensor is sensitive to smoke and to the following flammable gases: The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a built-in potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.
The MQ-3 alcohol sensor is, in fact, sensitive to other gases, besides alcohol. But we found a way to determine only the alcohol levels in the air. According to its datasheet, the MQ-3 alcohol sensor detects 25 to 500 ppm of alcohol (ethane). Here’s the graph of voltage vs. alcohol concentration:
