Introduction: MQ2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, ibutane, propane, methane ,alcohol, hydrogen and smoke. MQ2 Gas sensor can detect or measure gasses like LPG, Alcohol, Propane, Hydrogen, CO and even methane. The module version of this sensor comes with

Based on the graph MQ2, the derivation of ppm formula will be: Y y1 = m( X x1) X= (yy1)/m + x1. X= (Rs/Roy1)/m + x1. log X =(log (Rs/Ro) y1)/m +x1. X =10^( (log (Rs/Ro) y1)/m +x1) *Note: X = ppm on the graph. Y= Rs/Ro ***The derivation formula are same and can be used for other types of MQ gas sensor. If you have any problem about the coding, you are welcome to ask any question in ...

20210506· Hello everyone! I need help very badly. I’m working on my first project with arduino and the MQ sensors, and I’m stuck at getting the ppm values. I’m building a rover that is controlled by android and senses methane and CO levels in mines. Everything is working perfectly apart from the fact that I’m unable to convert the analog values to ppm. CO is not a big issue because I only want ...

20190606· When the smoke concentration is above 1000 ppm, the circuit triggers a buzzer that can be changed in the code as required. This project uses the MQ2 …

I have an mq2 sensor plugged into my homeduino and pimatic displays the analogue reading using the homeduinoAnalogSensor plugin. However I would like to convert this to the relevant gasses and their 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.

Regarding PPM calculation, first thing you should notice is that the relationship between RS/R0 and PPM is given on loglog scale. The second thing is that the graph in this scale is approximately linear. There are several methods to deal with this. You can take the graph from datasheet and plot it on linear scale. The result would be exponential curve and you can use various tools to find ...

The MQ2 Gas sensor has a builtin variable resistor that changes its value according to the concentration of gas. If the concentration is High, the resistance decreases, if the concentration is low, the resistance increases. Besides the builtin resistor, it is necessary to include load resistor, Load resistor serve to adjust sensor sensitivity and accuracy, it’s value can range from 2k ohm ...

The concentration of a gas is given in PPM (parts per million). One difficulty of the MQ2 is that a single analog value is given with which the gas content in the air has to be calculated for the various supported gases. However, the sensor must be configured for this purpose. Since this manual is also applicable to another Raspberry Pi gas sensor, the procedure is as follows: First, we have ...

The MQ135 is a cheap sensor and not ...

The concentration (ppm) of gases is calculated based of the resistance ratio (RS/R0). RS is the measured change in resistance when the sensing mechanism detects gas and R0 is the stable sensor resistance in fresh air or no gas presence.
