Carbon Monoxide Sensors | CO Sensor | Alphasense

Carbon monoxide (CO) is a particularly dangerous toxic gas, not only because it has no colour, no taste and no odour but because it is common in populated areas as a result of the burning of fossil fuels in vehicles and heating systems. Despite advances in detection, CO, or ‘the silent killer’ as it is often referred to, is still responsible for tens of thousands of deaths each year.

How to Use the MQ-7 Carbon Monoxide Sensor | Microcontroller Tutorials

According to its datasheet, the MQ-7 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 tutorial, I will be using the MQ-7 breakout board which has …

Carbon monoxide Levels that Sound the Alarm | Kidde

A carbon monoxide (CO) alarm is a time-weighted alarm. The way a time-weighted alarm works is by measuring the buildup of carbon monoxide in a house. For a person to begin feeling the effects of carbon monoxide poisoning, they would need to be exposed to a carbon monoxide level of 50 parts per million (PPM) for eight hours.

What levels of carbon monoxide (CO) will cause an alarm?

First Alert’s carbon monoxide alarms are designed to alarm before there is an immediate life threat. Underwriters Laboratories Inc. Standard UL2034 requires residential CO alarms to sound when exposed to levels of CO and exposure times as described below. They are measured in parts per million (PPM) of CO over time (in minutes).
