سنسور MQ2 Raspberry PI

ماژول سنسور تشخیص دود و گاز MQ-2

MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas. This change in the value of resistance is used for the detection of gas. MQ2 is a metal oxide …

raspbian - Problems Regarding Raspberry Pi Project with MQ-2 …

14/04/2015· My problem now is the output value of smoke sensing system with Raspberry Pi based on the code above only represents one single value. It doesn't distinguish between smoke level, LPG level, and other flammable gases. Some youtube videos show me that arduino can actually show different values at the same time. So what should I add or do to the python code above in order to distinguish …

How to build a LM393 MQ-2 smoke sensor circuit with a Raspberry Pi …

Raspberry Pi doesn't have any analog Pin so you will need an external ADC. so there are two option. get an external ADC with inbuilt amplifier. I will say look into ADS1115. the other option is go with a MQ2 sensor which comes with an on board Analog chip. So this will be the best way to go. you can look into this MQ2 gas sensor this one comes with I2C, so its easy to use and no need to use an external amp. …

Build Smoke Detector with Raspberry Pi | High Voltage Code

09/09/2019· So the fuil circuit as follows : Raspberry PI -> Logic Level Shifter -> ADC -> MQ2. This schematic should be self explanatory, but just to make few things clear, the red wire is 5 V which are provided by our RPi, but you can use an external power supply if you wish. Also notice the that we have to provide to Logic Level Shifter by connecting orange wire to LV and then 5V to HV.. The black …

MQ-2 Gas Sensor + Arduino: How to Detect Dangerous Fumes …

05/06/2019· 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. How Does the MQ-2 Work? The sensor’s voltage output varies proportionately with the measured smoke/gas in the atmosphere. In other words, the relationship between voltage and gas …
