prana air co sensor gas detector

CO Sensor 0.1 PPM Resolution

The best method for measuring CO gas is electrochemical technology. When an air sample from the co sensor contacts the working electrode, a chemical reaction takes place that either causes electricity to be produced through oxidation or reduction. The amount of carbon monoxide in the sample has a direct relationship to the amount of electricity produced.

What are its unique features?

co sensor compact icon


Easy to lodge in any device/ instrument due to its small size and ultra-thin packaging. The sensor is ideal for both handheld devices and real-time outdoor monitoring.

prana air co sensor durability


The operational life of sensor is up-to 10 years and is highly accurate.

co sensor highly responsive icon

Highly Responsive

15 seconds is average responsive time for sensor making the senor swift and robust. Hence, this is a good choice for real time monitoring.

Energy Efficient co sensor

Energy Efficient

Sensor demands low power input (0 mW at 0 mV bias) for its function. This decreases the overall energy consumption.

co sensor calibration

Individual Calibrated

Individual calibration service procures readings with the highest accuracy for every device the sensor is put in.

co sensor RoHS Complaint

RoHS Compliant

The sensor is in compliance with the Restriction of Hazardous Substances Directive (RoHS) for electrical and electronic equipment.

Technology We Use

What technology is being used in CO Sensor?

Electrochemical gas sensing is employed by Prana Air CO sensor. A working electrode, a counter electrode, and an ion conductor make up its primary parts. As CO reaches the sensor, it mixes with electrolytes and oxidises, producing water molecules and ions. As a result, current is produced by sensors.

The directed flow of electrons over the wire produces an electric current that is inversely proportional to the gas concentration. The movement of current between the two electrodes is picked up by the gas sensor.

Sensor Calibration

Comparing the measurement made with your equipment or device to the actual/standard measurement is the process of calibration. The equipment or instrument should be calibrated to increase accuracy and measurement traceability. To correctly calibrate the sensor, it is exposed to CO in the desired range. The sensor’s response is then compared to that of a reference Infrared Radiation (IR) CO analyser. The NIST gas cylinder standard is used to compare the target gas to. The standard environmental conditions for sensor calibration are 23 + 30 °C, 50 + 15% relative humidity, 0.9–1.1 atm pressure, and 0.05 m/s air velocity. Changes in the surroundings may impair the sensor’s sensitivity, although this may be easily fixed.

Frequent Asked Questions

1. Will this sensor come along with a digital board or not?

The sensor does not come with a digital board but if it needed, an additional purchase of a digital board along the controller is recommended. Prana Air provides a USB micro controller and a digital board which both have to be attached.

2. What conditions are used for calibration for CO sensor?

The standard environmental conditions for sensor calibration used are 23 + 3oC temperature, 50 + 15% relative humidity, 0.9-1.1atm pressure and air velocity of 0.05m/s. The alteration in environmental conditions may affect the sensitivity of sensor but is easily compensated.

3. What is the duration of warranty for this sensor?

Prana Air provides sensor with 6 months warranty only on manufacturing defects.

4. What is the mode of connectivity of the sensor to the board?

The sensor has to be connected to a digital board with a micro controller like the DGS to the USB to UART Bridge.

*Note: Prana Air provides the solution for the connectivity of the sensor through a USB miro controller and digital board.

5. How dangerous is carbon monoxide?

As per OSHA guidelines, the personal exposure limit of CO is 50 ppm. This level increases up to 12,800 ppm. Exposure to high levels can generate fatal symptoms, and can cause brain damage, heart problems, and breathing difficulties. When a pregnant woman is exposed to CO, the chances are the fetal blood cells with accept CO and will cause fatal CO poisoning.

6. At what places I am at high risk of CO exposure?

The risk of CO exposure is high in parking lots, garages, paint manufacturing industries, and if the crowd is having a high percentage of smokers. Even in house kitchens, the exposure to CO is high due to chimney installations.

7. What are the symptoms of CO poisoning?

The most common symptoms of CO poisoning involve headache, chest pain, confusion, vision impairment, nausea, and dizziness.
