Air Quality Sensors for Malaysian Schools: Tackling the Haze Problem with Real-Time Indoor Air Quality Monitoring

How Air Quality Sensors Can Help Malaysian Schools During Haze

Haze is a recurring environmental challenge in Malaysia, particularly during periods of elevated particulate pollution caused by regional forest fires, agricultural burning and other sources.

For schools, haze presents a unique challenge. Students and teachers can spend six to eight hours a day indoors, but simply closing windows and doors does not guarantee that indoor air quality remains safe or comfortable.

This is where air quality sensors and real-time environmental monitoring can make a significant difference.

By deploying Verkada air quality sensors throughout classrooms and other occupied areas, schools can continuously monitor indoor environmental conditions and make informed decisions about ventilation, air conditioning and classroom occupancy.

Instead of relying solely on outdoor haze readings or waiting for complaints about poor air quality, school administrators can gain visibility into what is actually happening inside the building.

What Is Indoor Air Quality Monitoring?

Indoor air quality (IAQ) monitoring involves continuously measuring environmental conditions inside a building.

Depending on the sensor and deployment, schools can monitor factors such as:

• PM2.5 particulate matter
• Carbon dioxide (CO₂)
• Temperature
• Relative humidity
• Other environmental conditions

For Malaysian schools, PM2.5 monitoring is particularly important during haze events because fine particulate matter can enter buildings through doors, windows, ventilation systems and other openings.

An indoor air quality sensor provides schools with real-time data that can help identify when conditions are deteriorating and where attention may be required.

Why Malaysian Schools Need Air Quality Sensors During Haze

During a haze event, many schools may respond by closing windows, reducing outdoor activities and increasing the use of air conditioning.

However, these measures do not automatically guarantee good indoor air quality.

A classroom may have:

• Elevated PM2.5 levels
• Excessive CO₂ due to high occupancy
• Poor ventilation
• High humidity
• Temperature issues

Without continuous monitoring, these conditions can be difficult to identify.

1. Monitor PM2.5 in Real Time

PM2.5 refers to very small airborne particles that are small enough to penetrate deep into the respiratory system.

During haze events, PM2.5 levels can increase significantly outdoors. Indoor concentrations can also rise depending on the building's construction, ventilation strategy, filtration and movement of people between indoor and outdoor areas.

With air quality sensors installed throughout a school, administrators can monitor PM2.5 levels in individual classrooms and occupied spaces rather than relying only on a single outdoor air quality reading.

2. Identify Problem Areas

Not every classroom or building within a school will have identical air quality.

For example, one classroom may have consistently higher particulate levels because it is located near an entrance, while another may have higher CO₂ levels because of occupancy and insufficient ventilation.

A distributed sensor network can help schools identify these differences. This allows facilities teams to determine which rooms require attention instead of treating the entire school as one environment.

3. Make Better Ventilation Decisions

Ventilation becomes more complicated during haze.

Opening windows can improve CO₂ levels but may also allow outdoor particulate matter to enter the classroom. Closing everything may reduce outdoor particulate infiltration but can contribute to rising CO₂ concentrations.

Real-time air quality monitoring gives school administrators more information when making these decisions. For example, if PM2.5 is elevated while CO₂ remains low, the school may choose to maintain its current ventilation strategy. If CO₂ rises significantly while PM2.5 remains controlled, facilities teams may need to review ventilation.

The important point is that decisions can be based on actual environmental data rather than assumptions.

How Verkada Air Quality Sensors Help Schools

Verkada provides a cloud-managed approach to building security and environmental monitoring, allowing organisations to gain visibility across multiple locations from a central platform.

For schools operating multiple buildings, campuses or classrooms, this can be particularly useful. Instead of checking individual standalone devices, facilities teams can use a centralised system to monitor environmental conditions across the school.

Centralised Visibility

A school may have dozens or hundreds of classrooms, offices, laboratories and common areas. A centralised monitoring platform can provide facilities teams with visibility into environmental conditions across these spaces.

This can help answer questions such as:

• Which classrooms currently have elevated PM2.5?
• Which areas have high CO₂ levels?
• Are air quality conditions improving or deteriorating?
• Which rooms consistently experience poor environmental conditions?

Having this information available centrally can make it easier for facilities teams to identify trends and prioritise corrective action.

Air Quality Monitoring Goes Beyond Haze

Although haze is one of the most obvious reasons for Malaysian schools to consider air quality monitoring, the benefits extend throughout the year.

CO₂ Monitoring

CO₂ levels can provide useful information about occupancy and ventilation. A classroom with high occupancy and insufficient fresh-air exchange can experience elevated CO₂ levels. Monitoring CO₂ can therefore help schools identify rooms where ventilation may need to be reviewed.

Temperature and Humidity

Temperature and humidity also influence classroom comfort. Monitoring these conditions can help facilities teams identify rooms that are consistently too warm, too cold or excessively humid. This information can also help schools optimise their air-conditioning and ventilation strategies.

From Reactive to Proactive School Management

One of the biggest advantages of environmental monitoring is the shift from reactive management to proactive management.

Without sensors, a facilities team may only discover an air quality problem after:

• Students or teachers complain
• A classroom becomes uncomfortable
• Outdoor haze levels become severe
• Someone manually checks the room
• An air purifier is found to be insufficient

With continuous monitoring, the school can identify changing conditions earlier. This creates a more proactive approach:

Monitor → Identify → Investigate → Respond → Verify

For school operators managing large campuses, this can make environmental management considerably more efficient.

How Air Quality Sensors Can Support Haze Management

A practical haze-management strategy for Malaysian schools could include several layers.

Step 1: Monitor Outdoor Conditions

Schools can monitor publicly available air quality information and local haze conditions.

Step 2: Monitor Indoor Conditions

Install air quality sensors in representative classrooms, offices and high-occupancy areas.

Step 3: Compare Indoor and Outdoor Conditions

Comparing indoor measurements with outdoor conditions can help facilities teams understand how effectively the building is controlling particulate infiltration.

Step 4: Identify High-Risk Areas

If certain classrooms consistently show elevated PM2.5 or CO₂ levels, facilities teams can investigate those locations.

Step 5: Take Corrective Action

Depending on the situation, schools may review:

• Air-conditioning settings
• Ventilation
• Air filtration
• Door and window usage
• Air purifier placement
• Classroom occupancy
• Building maintenance

Step 6: Verify the Results

After corrective action, sensors can continue monitoring the environment to determine whether conditions have improved. This final step is important because schools can measure the result rather than simply assuming the problem has been solved.

Where Should Air Quality Sensors Be Installed in a School?

Sensor placement should be based on the school's building layout and objectives.

Potential locations include:

• Classrooms
• Libraries
• Computer rooms
• Laboratories
• Staff rooms
• Meeting rooms
• Indoor activity areas
• Canteens
• Administration offices
• High-occupancy common areas

For larger campuses, schools can deploy sensors across multiple buildings to create a broader picture of indoor environmental conditions. Strategic placement is important. Installing sensors only in one room may not accurately represent conditions throughout an entire campus.

Air Quality Sensors + Smart Building Technology

Air quality monitoring becomes even more useful when combined with other building technologies. For example, a school may already have:

• CCTV
• Access control
• Environmental monitoring
• Air-conditioning systems
• Network infrastructure
• Building management systems

A connected technology ecosystem can provide facilities teams with a broader view of how buildings are being used and how environmental conditions are changing. This is particularly valuable for larger education groups managing multiple campuses.

Frequently Asked Questions About Air Quality Sensors in Malaysian Schools

A Smarter Approach to Haze Management for Malaysian Schools

Haze management should not rely solely on outdoor air quality readings.

The more important question for school administrators is:

"What is the air quality inside our classrooms right now?"

Air quality sensors provide the visibility required to answer that question. By continuously monitoring PM2.5, CO₂, temperature and humidity, schools can gain a better understanding of their indoor environment and make more informed decisions about ventilation, filtration and building operations.

For Malaysian schools, this means moving from simply reacting to haze toward a more proactive, data-driven approach to indoor air quality.

Conclusion

Haze is a recurring challenge in Malaysia, but schools do not have to manage indoor air quality blindly.

Verkada air quality monitoring can provide schools with real-time visibility into environmental conditions across classrooms and other occupied spaces.

When combined with appropriate ventilation, filtration and building-management practices, air quality monitoring can help schools create a more informed and proactive strategy for managing haze and maintaining healthier indoor environments.

For schools, universities and education groups looking to modernise their facilities, air quality monitoring is an important component of a smarter, safer and more data-driven campus.
