Senseware's Indoor Air Quality (IAQ) and Indoor Environmental Quality (IEQ) Sensor Packages makes it easy to deploy and monitor a variety of environmental conditions in seconds. These packages can provide the following sensor data depending on your ordered configuration:
Temperature, Relative Humidity
Total Volatile Organic Compounds (TVOC)
Particulate Matter (PM1.0, PM2.5, PM10, and total number of counted particle sizes)
Add-on gases: CO, H₂S, SO₂, O₃, NO₂, HCHO (Formaldehyde)
Plug the Sensor Package into a wall outlet using the provided wall power adapter (4-5 feet above the ground). The CO₂ and VOC sensors automatically calibrate and will reach full operational accuracy within 24-48 hours, although readings will be available before this time.
Note: Be sure to mount the IAQ enclosure vertically, not horizontally, in order to ensure proper airflow for accurate temperature/relative humidity readings when other sensors are present.
If your Indoor Air Quality bridge is version 3.4.5 then you can manually calibrate your CO, H₂S, SO₂, O₃, and NO₂ sensors to 'zero' when in clean air by performing a hard reset. For other versions of the sensor, please contact Senseware in regards to manually zeroing or spanning the sensor.
Beginning at version 3.4.6. the IAQ bridge will automatically offset using baseline values for CO, H₂S, SO₂, O₃, and NO₂ sensors. Once powered, the minimum values will be measured over increasing periods of time in order to automatically offset the sensor data using the calculated baseline levels. This process will become more accurate the longer the sensor is powered; the process will begin anew if the package gets unpowered. This functionality is not suitable in environments will persistently elevated levels of the measured gas; please contact Senseware if this will be the case to discuss other calibration options.
