# 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

## Status Indicators

| Status         | Description                           |
| -------------- | ------------------------------------- |
| **Online**     | Device connected and transmitting     |
| **Offline**    | Device not connected                  |
| **Monitoring** | Actively measuring (normal operation) |

## 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

See [Automation Rules](file:///automation/rules.md) for details.
