Sep 15, 2020· In this tutorial I show you how to use the MQ2 gas sensor with your Arduino, ESP8266 or ESP32 microcontroller. After we dive into the functionality of gas sensors in general, we build a gas alarm with the MQ2 gas sensor that detects smoke and turn on an active buzzer as alarm.
This article is a continuation of the series of tutorials on the PIC16F877A Microcontroller. The aim of this series is to provide easy and practical examples that anyone can understand. In the previous tutorial, we have interfaced the Rain detecting sensor with this tutorial, we are going to see LPG Gas Sensor Interfacing with PIC16F877A.
The Grove - Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect H2, LPG, CH4, CO, Alcohol, Smoke, Propane. Based on its fast response time. Measurements can be taken as soon as possible. Also the sensitivity can be adjusted by the potentiometer.
For detailed information about the MQ-9 sensor, please refer to the data-sheet provided in resource section. Getting Started . Connect the Grove - Gas Sensor(MQ9) to A0 port as shown in the above picture. Gas Detection : Basic Example. In this example, the sensor is connected to A0 pin. The voltage read from the sensor is displayed.
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.
