prana air co sensor 500 ppm range

CO Sensor (0.1 PPM Resolution)

Prana Air CO sensor uses electrochemical technology using the most effective means of monitoring CO gas. The co sensor collects a sample of air, and when it reaches the working electrode, a chemical reaction occurs, producing electricity via oxidation or reduction. The quantity of power generated is proportional to the amount of carbon monoxide in the sample.

– Electrochemical technology-based

– Range up to 500 PPM

– In compliance with ROHS

– 20mm x 20mm dimension

Prana Air 1 ppb carbon monoxide sensor

CO Sensor (1 PPB Resolution)

What are the unique features of CO Sensor?

 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 sensor durability


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

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 sensor

Energy Efficient

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

sensor calibration

Individual Calibrated

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

sensor RoHS Complaint

RoHS Compliant

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

What technology is being used in CO Sensor?

The CO gas sensor uses electrochemical gas sensing. Its main components are a working electrode, a counter electrode, and an ion conductor. CO combines with electrolytes and oxidizes to generate water molecules and ions as it reaches the sensor. Sensors produce current as a result of this.

The electric current created by the directed passage of electrons across the wire is precisely proportional to the gas concentration. The gas sensor detects the passage of current between the two electrodes.

CO Sensor Calibration

Calibration is the process of comparing the actual/standard measurement to the measurement taken with your equipment or device. Calibrating the equipment or instrument improves its accuracy and measurement traceability. The sensor is subjected to CO in the range of interest to precisely calibrate it, and its response is compared to that of a reference Infrared Radiation (IR) CO analyzer. The target gas is compared to the NIST gas cylinder standard. Sensor calibration is carried out under normal ambient settings of 23 + 30°C, 50 + 15% relative humidity, 0.9-1.1 atm pressure, and 0.05m/s air velocity. The sensor’s sensitivity may be affected by changes in the environment, however, this is readily corrected.

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.
