Description

Signal Analysis

The following algorithm results are given for ZMOD4410 and RRH46410:

▪ IAQ 2nd Gen (Absolute and Relative):

The IAQ rating from the Federal German Environmental Agency (UBA)

ranging from 1 (Clean Hygienic Air) to 5 (Unacceptable Conditions) and is

based on an absolute TVOC reading (mg/m3 or Ethanol equivalent in ppm).

Also, a relative IAQ indicates general changes in air quality:

● 0 to 100

Improvement in Air Quality (air gets cleaner)

● 100

No change in Air Quality

● 100 to 500

Degradation in Air Quality (air gets more polluted)

▪ PBAQ:

The PBAQ operation mode complies with typical Public Building Air Quality

standards. It focuses on high accurate TVOC concentrations in the typical

indoor environments and is given in absolute numbers (mg/m3) and as

relative output (same scale as IAQ 2nd Gen). Also, a relative PBAQ output

indicates general changes in air quality:

● 0 to 100

Improvement in Air Quality (air gets cleaner)

● 100

No change in Air Quality

● 100 to 500

Degradation in Air Quality (air gets more polluted)

▪ Sulfur Odor Discrimination:

Identifies bad sulfur odors. The algorithm output is classified as

“acceptable” and “bad” with an intensity indicator ranging from 1 (clean air)

to 5 (very strong)

The following algorithm results is given for ZMOD4510:

The first 50 measurement samples will be taken for sensor stabilization.

During this time, the “Algorithm Result” section will indicate the completion

progress and will continually show the sensor resistance. After stabilization,

the ozone and nitrogen dioxide concentrations are given (in ppb) and the AQI

is shown in six categories according to the EPA Air Quality Standard:

▪ 0 to 50

Good Air Quality

▪ 51 to 100

Moderate Air Quality

▪ 101 to 150

Unhealthy Air Quality for Sensitive Groups

▪ 151 to 200

Unhealthy Air Quality

▪ 201 to 300

Very Unhealthy Air Quality

▪ > 300

Hazardous Air Quality

The following algorithm results are given for HS3001 and HS4001:

Temperature (°C) and Humidity (RH).

Returns the values for relative humidity (RH) in % and temperature in °C in

the selected sample interval.

The following algorithm results are given for RRH62000:

The All-in-one Air Quality Module includes sensing elements for Particle

Measurement (PM1, PM2.5, and PM10), TVOC, IAQ, eCO2, Temperature,

and Humidity. The PM measurement has two output options: KCl (Potassium

Chloride, a typical calibration particle nuclei) and Smoke (Cigarette smoke,

used for calibration).
