This is a simpletouse compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ4 can detect natural gas concentrations anywhere from 200 to 10000ppm. Sensitive material of the MQ4 gas sensor is SnO2, which with lower conductivity in clean air.

20190721· Add a sensor and some Python 3 to your Raspberry Pi to keep tabs on your local air pollution, in the project taken from Hackspace magazine issue 21. Air is the very stuff we breathe. It’s about 78% nitrogen, 21% oxygen, and 1% argon, and then there’s the assorted ‘other’ bits and pieces – many of which have been spewed out by humans and our related machinery. Carbon dioxide is ...

20190909· Besides Raspberry Pi, for this project we will need: MQ2 LPG Ibutane Propane Methane Alcohol Hydrogen Smoke Gas Sensor Module ~ 16 Bit I2C ADS1115 Module ADC 4 channel with Pro Gain Amplifier ~ 2 Channel IIC I2C Logic Level …

Using this module you can easily interface MQ4 Methane (CNG) gas Sensor to any Microcontroller, Arduino or even Raspberry Pi .Since this Gas Sensor module is sensitive to Methane it is also small sensitivity to alcohol smoke.

20190821· A singleboard Raspberry Pi (originally developed to assist in computer technology needs in poor countries) works great as a controller for a bunch of single program operational microcontrollers like Arduino’s that can be looped indefinitely and will do simple and repetitive tasks.

20210923· Knowles Corp. has launched a Raspberry Pi development kit that will allow engineers to bring voice, audio edge processing and machine learning capabilities to internet of things (IoT) applications. The Knowles AISonic IA8201 kit allows designers, makers and engineers to have a single tool to streamline design, develop and test the technology. The kit is powered by Knowles auto edge …

sensor functions and how to set up the sensor for use on a Raspberry Pi. How does the MQ 2 work? Figure 1: MQ2 Gas Sensor Figure 2: Schematic of MQ2 Gas Sensor from Datasheet. 2The MQ 2 sensor is a metal oxide semiconductor (MOS), also known as a chemiresistor. MOS sensors measure the change in resistance when gases are present. This type of sensor requires the gas to encounter …

20200911· MQ4 Methane Sensor Overview. At the heart of the MQ4 is a heater and electrochemical sensor. When the target gas enters the membrane and reaches the sensor, it undergoes a redox reaction which creates current. This current is stronger for sensors at specific gases. In the case of the MQ4, it’s more sensitive to methane, butane and propane.

It detects many different gases like propane, LPG, methane, etc... I''m trying to use it to detect the presence of methane but I can''t quite understand the reading returned by the sensor. Currently the gas reading returns an integer between 0250. However, it doesn''t indicate which of all the gases it''s reading or what exactly is the concentration (in ppm) of said gas.

20160818· ADC121C_MQ4. ADC121C_MQ4 Gas Sensor. The MQ4 is capable of sensing methane or natural gas air concentration levels. This Device is available from [SKU: ADC121C_I2CGAS_MQ4]

20160513· The sensor works using either serial communication or via the I2C protocol, for this example, I will be configuring the sensor to use the I2C interface on the Raspberry Pi. To configure the Pi I am assuming that you are running the latest version of Raspian , have the ability to connect to your Pi either through SSH with putty and FTP with Filezilla , or directly with a keyboard and monitor.

This methane gas sensor detects the concentration of methane gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. For example, the sensor could detect if someone left a gas stove on but not lit. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V. Please ...

20180604· Raspberry Pi Gas Sensor Setup. To set up the gas and flame sensor I used the PCF8591 ADC converter to generate numerical readings. The Gas sensor and Buzzer were wired as shown below.
