Carbon monoxide detector Wikipedia

A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas to prevent carbon monoxide the late 1990s Underwriters Laboratories changed the definition of a single station CO detector with a sound device to carbon monoxide (CO) applies to all CO safety alarms that meet UL 2034 standard; however for passive indicators ...

What could cause a negative reading on a CO sensor? | GfG ...

Carbon monoxide sensors are normally very stable. They are cross sensitive to a couple of potential interfering gases, however. Usually negative readings are the result of the CO sensor being fresh air adjusted while in the presence of a detectable interfering gas, or when the sensor is fresh air adjusted before it has completed recovering from a prior exposure to an interfering gas. The CO ...

Why is hydrogen such a big issue for CO sensors? | GfG ...

CO sensors also respond strongly to acetylene gas. Since the internal filter does not absorb acetylene, the sensor shows a very strong and immediate response to this gas. GfG Technical Note 2019, “G460 and Micro IV electrochemical (EC) toxic sensor relative response matrix” includes a chart listing some of the most common documented interferences for the electrochemical sensors used in GfG ...

How to Use the MQ7 Carbon Monoxide Sensor ...

Introduction to MQ7 Carbon Monoxide Sensor. According to its datasheet, the MQ7 carbon monoxide sensor detects 20 to 2000 ppm of CO in air. Here is its sensitivity characteristic curve: This is a graph of Rs/R0 vs. gas concentration in ppm. Rs is the resistance of the sensor in target gas while R0 is the resistance in clean air. We will use this graph later when we create our code. For this ...

At What Height Should Sensors be Mounted?

The sensor mounting height depends the type of application and on the density of the gas relative to air. Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed in the "breathing zone" 4 6 feet from the floor ...
