· The IR LEL sensor is designed primarily for a target gas ( Methane, Propane). It can detect a variety of gases with a greater or lesser degree of accuracy, but cannot be adjusted with a correction factor. Only the manufacturer can specify which gases the sensor can read and the expected reading level.
MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas.
Sensoric toxic gas sensors have gained worldwide recognition for excellent performance, particularly for detecting exotic gases. Sensors are available in a small ‘mini’ housing or can be supplied with adaptors to fit the 4 and 7Series format. Sensoric sensors are also available with 4 mA to 20 mA transmitter boards. Data Sheet.
The VOC sensor was designed to monitor common indoor air quality contaminants only. There are several gases that will affect the sensor reading but are not typical indoor contaminants. Typical outdoor gases such as SO2, H2, and CO will affect the sensor but have not been tested.
Aug 07, 2017· The response of the IR sensor is nonlinear and only becomes linear once the sensor is characterized to a particular gas. Response factors between gases also vary greatly and can be more than 10 in some cases. If a gas with a response factor of ≥10 is encountered, the instrument will produce a false alarm when the actual gas concentration was ...
Apr 02, 2021· The following is a list of different types of sensors that are commonly used in various applications. All these sensors are used for measuring one of the physical properties like Temperature, Resistance, Capacitance, Conduction, Heat Transfer etc. Temperature Sensor. Proximity Sensor…

Feb 16, 2018· If we suppose to measure the concentration level as for the carbon monoxide, via a MQ7 sensor, the gas level might be misrepresented because of the presence (or absence) of other gases the sensor reacts to (such as, for example, the hydrogen). However, the limited cost of the sensor makes it very useful for many projects, so that we may ...
Aug 18, 2021· What is a gas sensor? Posted on August 18, 2021. In simple terms, a gas sensor is a device capable of responding to the presence of gas defined by certain parameters..
