Carbon Monoxide Sensor Variant A

The Prana Air CO sensor uses advanced electrochemical technology to detect carbon monoxide (CO) in the air. It works by taking a small sample of air and reacting with it inside the sensor. When CO is present, a chemical reaction happens that creates a small electric current. The strength of this current shows how much carbon monoxide is in the air — the more CO, the stronger the signal.

Sensor Calibration

Calibration means checking how accurate a device is by comparing its readings to a known standard. This helps make sure the sensor gives correct and reliable results. To calibrate the CO sensor, it is tested with carbon monoxide within the required range and its response is compared to a trusted reference device (an IR CO analyzer). The gas used is also matched with a standard from NIST (National Institute of Standards and Technology). Calibration is done in normal room conditions — around 23°C, 50% humidity, standard air pressure, and a gentle airflow. If the environment changes, it might affect the sensor slightly, but this can be easily adjusted.

What is Carbon Monoxide (CO)?

Ammonia source image

Carbon monoxide (CO) is a colourless, odourless, and tasteless gas that can be harmful or even deadly when inhaled in large amounts. It is produced by burning fuels like gas, wood, coal, or oil. Because it's hard to detect without sensors, monitoring CO levels is important—especially in homes, vehicles, and industrial areas—to ensure air safety and prevent carbon monoxide poisoning.

What technology is being used in CO Sensor?

Technology working image

The CO sensor uses electrochemical technology to detect carbon monoxide gas. Inside the sensor, there are three main parts: a working electrode, a counter electrode, and a special liquid (electrolyte) that helps the reaction happen. When carbon monoxide enters the sensor, it reacts with the liquid and creates water and tiny particles called ions. This reaction produces a small electric current. The more carbon monoxide there is, the stronger the current. The sensor measures this current to know how much CO is in the air
