The 9 in 1 gas sensor module kit you mentioned is a collection of nine different gas sensors that are designed to detect a wide range of gases. Each sensor in the kit is based on a different chemical principle and is optimized to detect a specific type of gas. The MQ-2 sensor, for example, is a flammable gas sensor that can detect propane, butane, and other flammable gases. The MQ-3 sensor is an alcohol sensor that can detect the presence of alcohol in the air. The MQ-4 sensor is a methane (natural gas) sensor, and the MQ-5 sensor is a carbon monoxide sensor. The other sensors in the kit can detect different gases such as hydrogen, oxygen, and ammonia.
These gas sensors are often used in air quality monitoring systems, gas leak detection systems, and other applications where it is necessary to detect the presence of specific gases in the air. They are typically connected to an electronic circuit or microcontroller, which can interpret the sensor's output signal and provide an indication of the gas concentration in the air.
This 9-in-1 gas sensor module kit is perfect to test for the presence of a large variety of gasses. All the modules are compatible with Arduino.
