· Hallo zusammen, ich versuche einen MQ-2 an einem D1 Mini ans laufen zu bekommen. Ich hab das in der Library enthaltene Sample kompiliert und hochgeladen. Ich benutze den A0 Anschluß um Daten zu empfangen. Leider bekomme ich komische Werte: LPG: CO: SMOKE: Wenn ich den analogen Anschluss trenne bekomme ich 0 Werte, also kommen die Werte vom MQ-2.
· Hi everyone ! , In my studies, I have a project where I use the MQ-2 gas sensor. here is the program I use: const int analogInPin = A0; // Analog input pin that the potentiometer is attached to const int ledPin = 13; // LED connected to digital pin 13 int sensorValue = 0; void setup() { // put your setup code here, to run once: (9600); pinMode(ledPin, OUTPUT); // sets the digital ...

· Gassensors. codes for mq2, mq3, mq4, mq5, mq6, mq7, mq8, mq9, mq135 gas sensors. contains the equations (temperature and humidity independent) that i have obtained based on the sensitivity characteristics graphs provided in the datasheets.
· 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
Me Gas Sensor includes a smoke sensor of type MQ2 which has good repeatability, long-term stability, short response time, and durable working performance. It is often used as a gas leakage monitoring device in family and factory, and suitable for detecting Liquefied Natural Gas (LNG), butane, propane, methane, alcohol, hydrogen, smoke, etc. Its black ID means that it has an analog port and ...

· In this illustration we will wire the GAS SENSOR MQ2 Module, these device is very useful for GAS leakage detection in home or industry it can detect H2, LPG, CH4, CO, Alcohol or Propane. This device is very sensitive and fast response time and measuring and also can be adjusted onboard by the trimmer potentiometer.
· 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.
· OK, I understand about the baseline for a gas. What I'm not clear about is that, for example, I set the baseline in my room. The room presumably wouldn't have much H2, …
Grove - Gas Sensor(MQ2) The Grove - Gas Sensor(MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer. Note. The sensor value only reflects the ...

MQUnifiedsensor. Sensors. This library allows you to read the MQ sensors very easily. This library allows an Arduino/Genuino/ESP8266 board to read MQ Sensors (AIr quality meter) references: MQ2, MQ3, MQ4, MQ5, MQ6, MQ7, MQ8, MQ9, MQ131, MQ135, MQ303A, MQ309A. Author: Miguel Califa.
· MQ2 - Reading different gases. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values - from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000.
· Tutorial Akses Sensor MQ-2 pada Arduino. Sensor MQ-2 merupakan sensor yang berfungsi untuk mendeteksi kandungan gas seperti Lpg, CO, asap dan masih banyak lainnya.
