Ozone O3 Sensor:

Prana Air provides best-in-class ozone O3 sensor and monitoring systems that can be used to precisely and accurately determine the concentration of ozone in the area.  Monitoring is the primary shield against ozone’s ill effect on our health. Electrochemical sensors are the industry standard for monitoring ozone. In this type of sensor electric current produced by the reaction of the gas sample with the electrolyte is measured to determine the concentration of ozone in the air. The direction of flow of the electron created an electric current which is proportional to the concentration of gas.

Ozone is a layer present in stratosphere of atmosphere. Ozone is a protective layer that protects from the harmful ultraviolet radiations coming into earth. However, the ozone layer that we breathe at ground level is hazardous. Ozone gas consists of three atoms of oxygen, colorless to pale blue in color. The odor of ozone is pungent and his highly combustible. The major source of ozone presence at ground level is due to ozone layer breaking. Other source includes automobiles emissions, construction, power plants, extraction and operation of oil, industrial boilers, chemical plants, coal and gasoline burning. It’s monitoring not only helps in determining air quality but also to warn if there is a high quantity where it should not have been.

Technology We Use

What technology is being used in Ozone Sensor?

Ozone sensors provided by Prana Air work on electrochemical gas sensing technique. The technique uses three principle components a working electrode, a counter electrode and an ion conductor. The ion conductor is a bridge between two electrodes. The passing of gas through the senor results in current generation between electrodes and this generated current is directly proportional to the concentration of Ozone in the environment.

The directional flow of electrons through the wire creates an electric current that is directly proportional to the concentration of gas. The gas sensor works by measuring this current flow between the two sensors.

Sensor Calibration

Calibration of a sensor is necessary to determine the accuracy and traceability of instrument and measurement respectively. The process in which standard measurement is compared with the measurement using your instrument or device is called Calibration. To accurately calibrate the sensor, the sensor is exposed to O3 in the range of interest for which NIST standard of gas cylinder is used as a reference. The calibration is performed under some standard environmental conditions like 23 + 3oC temperature, 50 + 15% relative humidity, 0.9-1.1atm pressure and air velocity of 0.05m/s.

What do we know about Ozone?

Oxygen is the essential component of our existence. But there is one compound of oxygen that is not only harmful but deadly for human and have adverse on our environment. It is usually found in the stratosphere about 15 to 30 km above the earth’s surface. In the stratosphere, it is very useful for human existence but at ground level, it is whole another story. It’s monitoring not only helps in determining air quality but also to warn if there is a high quantity where it should not have been.

O3 is a gas composed of 3 oxygen atoms found in both at upper as well as the ground level of the atmosphere. It is very important at the upper level or stratosphere as it absorbs the sun’s harmful UV lights. But at ground level, it causes photochemical smog in presence of sunlight. It is colorless, mildly soluble in water, and highly combustible. Ozone smells mildly like chorine. It is both natural and manmade.

Ozone sources are different for both the stratosphere and troposphere(ground level). In the stratosphere, ozone is formed by the Chapman cycle in which O2 is excited by photon and produces independent oxygen atoms which inturn reacts with atmospheric O2. In this process, O3 is produced in the stratosphere where it helps reflect harmful UV from the sun.

Human sources of ozone include:
– Automobile emissions
– Construction activities
– Power plants
– Oil extraction and operation
– Biogenic sources

– Whenever there is a warning of high ozone levels. ventilate the room or vacate immediately.
– Avoid idling of automobile
– Reduce the frequency of trips
– Use alternate fuel options like battery-operated vehicles or hydrogen-powered vehicles.
– Avoid any unnecessary physical activity outside when there is a high concentration of ozone
– Avoid spillage of fuel as it aggravates the formation of ozone.

Impacts of O3 Gas on Health & Environment

Let’s find out how harmfule the ozone gas to our health.

It affects the respiratory system adversely and causes inflammations. It causes shortness of breath and cough which aggravate breathing-related diseases. children and people over 65 are more susceptible to its adverse effects along with people who work or exercise outside. Patients with cardiovascular history can be highly affected so for them monitoring of ozone is very important.

– Coughing, sore throat

– Constriction and inflammation of airways

– Asthma, emphysema, bronchitis

– Increased susceptibility of lung infections

– Capable to react with free radicals and oxidant species

– Can react with different types of cell such as neural, immune and epithelial in lungs airway

A high concentration of ozone affects the flora and fauna of the area. Ozone also participates in photochemical ozone formation which reduces visibility.

– Reduces the process of photosynthesis and growth in plants

– Increases risk of disease, damage by insects on plant, leaves

– Species diversity loss

– Changes in nutrients and water cycle in environment

– Reduction in agricultural output and commercial forest yields

– Induces stressors like harsh weather, smog

Frequently Asked Question
(FAQs)

1. Does this sensor come along a digital board?

The user has to option to choose either the sensor only or both sensor and board. Prana Air has a USB digital board with a micro controller.

2. What conditions are used for the calibration of ozone 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 warranty period of the sensor?

The sensor has 6 months warranty only on manufacturing device.

4. How do I connect the sensor to the board?

The sensor has to be connected through a USB micro controller and digital board to UART Bridge.

5. Is ozone a pollutant or a Green House gas?

Ozone is both an air pollutant and Green House gas. The depletion of protective ozone layer is causing the increased heating of earth’s surface. The ground level ozone is formed due to photochemical reaction between VOCs and NOx in presence of heat and sunlight.

6. How do I protect myself from ozone exposure?

Use Prana Air’s monitors to continuously monitor the levels of ozone, avoid spending too much time outside when the concentration is high, avoid continuous travel and trips.

7. What is the safe level range of ozone for exposure?

According to NIOSH and OSHA, the recommended limit of exposure is 0.1ppm or 0.2 mg/m3. However, the levels higher than or equal to 5ppm is considered hazardous and dangerous to life. (NIOSH).

8. What adverse effects I can experience after being exposed to high level of ozone?

Adverse effects of ozone exposure can include severe lungs infection attacking the neural, epithelial and immune cells, eye irritation, conjunctivitis, inflammation in tissues of lungs, reduction in ability to breathe.

9. Which type of industries or places has high level of Ozone?

Ozone levels elevate in the afternoon because the exhausted fumes from the morning rush hour have reacted with sunlight. People working in power points, industrial boilers, oil and petroleum refinery, chemical plants are exposed to high level of ozone.
