Not enough oxygen to produce carbon dioxide (CO ), such as when operating a stove or an internal combustion engine Neurological signs include confusion, disorientation, visual disturbance, syncope, and seizures.Ĭarbon monoxide is produced from the partial oxidation of carbon-containing compounds it forms when there is The most common symptoms of CO poisoning is headache, nausea, vomiting, dizziness, fatigue, and a feeling of Have no idea that they are breathing in CO besides the fact that they would start to feel horrible.

This is a sensor that is sensitive toĬarbon monoxide (CO) is a very dangerous gas which is odorless, colorless, and tasteless, The carbon monoxide sensor we will use is the MQ-7 sensor. In this project, we will go over how to build a carbon monoxide sensor circuit with an arduino.

MQ135 – Air Quality (CO, Ammonia, Benzene, Alcohol, smoke)Īir quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. MQ135 gas sensor has high sensitivity to Ammonia, Sulfide and Benze steam, also sensitive to smoke and other harmful gases.MQ-7 Carbon Monoxide Sensor Circuit Built with an Arduino

Detection Range: 100 – 10,000 ppm H2 (Hydrogen).

The sensor’s output is an analogue resistance. This sensor has a high sensitivity and fast response time. The MQ-8 can detect hydrogen petrol concentrations anywhere from 100-10000 ppm. This is a simple-to-use hydrogen petrol sensor, suitable for sensing hydrogen concentrations in the air.

Dimensions: 18mm Diameter, 17mm High excluding pins, Pins – 6mm.

Detection Range: 300-10000 ppm( Combustible gas).

The analog gas sensor – MQ2 is used in gas leakage detecting equipment’s in consumer and industry markets, this sensor is suitable for detecting LPG, I-butane, propane, methane ,alcohol, Hydrogen, smoke.

Here is a list below of the different Gas Sensor Module MQ-2 MQ-8 MQ135 MQ-2 – Methane, Butane, LPG, smoke
