The BACnet Particulate matter Sensor for indoor applications combines the measurement of temperature, relative humidity, and particulate matter (PM2.5) detection. This multi-sensor device supports both BACnet MSTP and BACnet IP protocols.
The ANB-THPM2.5 is designed for building automation in offices, schools, healthcare facilities, residential buildings, industrial sites, and public spaces.
Communication protocols supported in ANB-THP2.5:
- BACnet MSTP
- BACnet IP
- Modbus RS485
Alternative BACnet sensor versions:
- ANB-T – Bacnet temperature sensor
- ANB-TH – Bacnet temperature, humidity sensor
- ANB-THPV – Bacnet temperature, humidity sensor, pressure, VOC
- ANB-THPC – Bacnet temperature, humidity sensor, pressure, CO2
- ANB-THPVC – Bacnet temperature, humidity sensor, pressure, CO2, VOC
- ANB-THPVCP – Bacnet multi sensor: temperature, humidity sensor, pressure, CO2, VOC, presence

How to Interpret PM2.5 Values: Air Quality and Health Effects
The PM2.5 sensor enables precise monitoring of the concentration of fine particulate matter in the air that is smaller than 2.5 micrometers. These particles are among the most important indicators of air quality in both indoor and outdoor environments, as they can penetrate deep into the respiratory system and negatively impact human health. Understanding the measured PM2.5 values is crucial for timely action and health protection, especially for sensitive population groups.
The table below shows how different concentrations of PM2.5 affect air quality and human health.
Table 1: PM2,5 specific AQI and cautionary statements defined by the EPA
| PM2.5 breakpoints (µg/m³, 24-hour average) | Air Quality Index (AQI) Category | Air Quality Index Description |
|---|---|---|
| 0.0 – 12.0 | Good | Air quality is satisfactory, and air pollution poses little or no risk. |
| 12.1 – 35.4 | Moderate | Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution. |
| 35.5 – 55.4 | Unhealthy for sensitive groups | Members of sensitive groups may experience health effects. The general public is less likely to be affected. |
| 55.5 – 150.4 | Unhealthy | Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects. |
| 150.5 – 250.4 | Very unhealthy | Health alert: the risk of health effects is increased for everyone. |
| > 250.4 | Hazardous | Health warnings of emergency conditions: everyone is more likely to be affected. |
