Hi peeps! Welcome to another tutorial where we are discussing the MQ sensor elements. Today, our focus is on the MQ131 ozone gas sensor. Ozone is a major component of air pollution and it leads to multiple health problems related to the respiratory system and other issues. It also has an adverse effect on the plants and agricultural lands. It is a pungent gas with a pale blue color and usually, it is present in very low concentrations in the normal air. The MQ131 ozone gas sensor is used in outdoor monitoring stations, industries that use ozone for experimentation, laboratories, and sensitive areas that have a high concentration of ozone gas in the environment.

Hey fellow! Welcome to the next article on the MQ series of sensors, and today our focus is on the MQ-8 which is used to sense the presence of hydrogen gas. We know that hydrogen is a colorless, odorless, and tasteless gas that humans can not sense easily. It is not toxic like carbon monoxide and other such examples but still, the excess presence of this gas can be life-threatening because it is highly flammable. The air is a mixture of different gases and hydrogen gas when combined with some specific gases, can be harmful to life. In the presence of a bare flame or other ignition material, hydrogen can start the ignition, and here, the duty of sensors like MQ-8 starts. We’ll examine the basic information about this sensor in detail. Libraries MQ-8 Simulation Libraries Latest library: MQ G ...
Hello peeps! I hope you are having a good day. We all know carbon monoxide is a dangerous and harmful gas that can even be fatal. It is a colorless and odorless gas so it is difficult to sense its presence therefore, different types of sensors and indicators are required to make the places safe especially those where there is a chance for carbon monoxide gas production as a byproduct. Here, one of the most promising detectors is the MQ-7 carbon monoxide sensor which instantly detects and indicates the presence so the users may save their lives. This is the most popular choice for this purpose because of its low cost, high performance, and instant response.

Hey pals! Welcome to the next article where we're studying a gas sensor from the MQ sensor series. Today, we’ll understand the MQ-6 LPG butane gas sensor and will know the basic information about this product. This sensor has sensitivity for gases like LPG, isobutane propane etc and it is widely used to check any leakage of these gases. These are the commonly used gases but any leakage or excessive use may be harmful and even life-threatening. In such cases, sensors like MQ-6 are proved one of the most important devices.

Hello readers! I hope you are doing great. Today we are discussing the features and details of the MQ-4 methane gas sensor, which belongs to the popular gas sensor MQ family. We have been working on other gas sensors as well, but MQ-4 is particularly suitable for detecting the presence of methane gas. This sensor is more popular because methane gas and compressed natural gas (CNG) are widely used for cooking and other related purposes. MQ-4 methane gas sensor is an important part of the home safety system. Some other advantages of this sensor are, that it responds instantly and has a potentiometer that adds versatility to its functions.
