Overview

AirWatch is KEMPER's welding fume and particulate matter monitoring sensor. It measures PM2.5 and PM10 concentrations in ambient air, providing real-time air quality data for industrial environments.

Device Variants

Variant	Slug	Description
AirWatch 3.0	airwatch-30	Standard model
AirWatch LTE Europe	airwatch-lte-europe	Cellular-connected (European frequencies)
AirWatch LTE America	kemper-airwatch-lte-america	Cellular-connected (American frequencies)

Purpose

AirWatch sensors are designed to:

• Monitor welding fume concentrations

• Track particulate matter (PM) levels

• Provide ambient air quality data

• Enable data-driven ventilation control

• Support occupational health monitoring

Key Measurements

Measurement	Unit	Description
PM2.5	µg/m³	Fine particulate matter (≤2.5 micrometers)
PM10	µg/m³	Coarse particulate matter (≤10 micrometers)
4h Average PM2.5	µg/m³	4-hour rolling average
4h Average PM10	µg/m³	4-hour rolling average
Total Particles	count/m³	Total particle count

Particle Size Distribution

AirWatch provides detailed particle size distribution across six bins:

Bin	Size Range
Bin 0	> 0.3 µm
Bin 1	> 0.5 µm
Bin 2	> 1.0 µm
Bin 3	> 2.5 µm
Bin 4	> 5.0 µm
Bin 5	> 10.0 µm

Measurement Type

AirWatch performs ambient (hall) measurement, meaning:

• Measures general air quality in the facility

• Not a point-source measurement

• Represents overall workplace conditions

• Distinct from Occupational Exposure Limits (OEL)

Use Cases

Air Quality Monitoring

• Track PM levels throughout the day

• Identify pollution patterns

• Compare against WHO guidelines

Automation Triggers

• Trigger filtration devices based on PM10 thresholds

• Integrate with AirDome and Clean Air Tower

• Automatic ventilation control

Compliance Support

• Historical data for audits

• Report generation

• 4-hour average calculations

Integration with Automation

AirWatch sensors can serve as triggers for automation rules:

• Set PM10 threshold (e.g., 100 µg/m³)

• Select target filtration devices

• Automatic start/stop based on air quality
