Grove - Gas Sensor(MQ2) - Seeed Wiki

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.

arduino - How to calculate Gas sensor PPM from analog ...

I am new to Arduino and electronics in am working on MQ 7 Gas sensor to test Carbon monoxide level. But the issue is i still can't grasp the concept of converting analog readings to PPM. I tried to follow this,but some parts, are very clear especially R0 = RS_air/(26+(1/3)) So far with my code below the ratio I get is between 20 and 30.

Blynk Smart Smoke Detector | MQ-2 Gas Sensor

Aug 17, 2021· This article will make our own smart smoke detector with an MQ2 gas sensor and NodeMCU. We can call it smart as it automatically detects the smoke and sends an alert notification to our smartphones. For controlling the MQ2 gas sensor we are using the Blynk app. Please check how you can set up your Arduino IDE to upload the code in NodeMCU.

MQ2 - Reading different gases - Sensors - Arduino Forum

May 06, 2021· 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.

Interface Arduino with Gas Sensor

Jul 30, 2021· In this article, we will see how to interface Arduino with the MQ-2 gas sensor. MQ2 gas sensor is used for detecting smoke and some flammable gases like LPG, Methane, etc. It changes its resistance depending on the type of the gas. This principle can be used to raise an alarm based on the concentration of the gas.

Arduino and MQ-2 (gas & smoke) sensor

Hooking up an MQ-2 (gas & smoke) sensor to an Arduino Uno via a breadboard. The wiring connection is important: Both A pins and the left H pin need to be connected to 5V. Both B pins need to be connected to the analog input (A0). The right H pin needs to be connected to the ground (GND). A load resistor from 2kOhm to 47kOhm needs to be ...
