MQ-6 gas sensor modules are used in gas leakage detecting equipments in family and industry, are suitable for detecting of LPG, iso-butane, propane, LNG, avoid the noise of alcohol and cooking fumes and cigarette smoke. Features. High sensitivity to CH4，Natural gas Small sensitivity to alcohol, smoke Fast response How to Use MQ2 Gas Sensor - Arduino Tutorial: 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. The MQ-1 Predator Unmanned Aerial vehicle (UAV) and sensors are controlled from the ground station via a C-band line-of-sight data link or a Ku-band satellite data link for beyond-line-of-sight operations. During flight operations the crew in the ground control station is a pilot and two sensor operators. @philicibine said in How to get convert mq2 reading to ppm?: I think I could take the variable and apply the arithmetic to it to convert the reading but I have no idea how to do this with pimatic. Well, for me, the tough bit would be to calibrate the sensor and to get the mapping function right. Where to use MQ-2 Gas sensor: The MQ-2 Gas sensor can detect or measure gasses like LPG, Alcohol, Propane, Hydrogen, CO and even methane. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas.

The MQ-3 is a heater-driven alcohol sensor that outputs an analog signal (usually interpreted somewhere between 150 and 1023 depending on how long you let the sensor warm up), which through the use of your Arduino code and calibration, can be interpreted for whatever use you need. The core sensing material of MQ-9 gas sensor is SnO2, which has a lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature (heated by 1.5V). The sensor’s conductivity is higher along with the gas concentration rising. Seeed 101020045 Grove - Gas Sensor for Carbon Monoxide (MQ-9) The Grove Carbon Monoxide Sensor from Seeed Studio can measure carbon monoxide in concentrations from 10 to 1000ppm. Its output is FREE Delivery Across UAE. FREE Returns. 5M+ Products. Description. The Grove sensor series features a set of inexpensive, interesting gas sensor modules. Here, the MQ9 sensor specializes detecting Carbon Monoxide, Coal gas (CH4), and Liquified Natural Gas vapour. TECHNICAL DATA MQ-2 GAS SENSOR FEATURES Wide detecting scope Fast response and High sensitivity Stable and long life Simple drive circuit APPLICATION They are used in gas leakage detecting equipments in family and industry, are suitable for detecting of LPG, i-butane, propane, methane ,alcohol, Hydrogen, smoke. May 05, 2016 · Example: Gas Sensor with Arduino. In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. Parts needed: So, for this example, you’ll need: 1 x MQ-2 gas sensor
