Common questions about monitoring parameters, module selection, sensor integration and IAQ device development.
Common sensor types include CO₂, particulate matter, VOC, formaldehyde, temperature and humidity sensors. The appropriate combination depends on the monitoring functions of the finished device.
CO₂ sensors measure carbon dioxide concentration. PM2.5 sensors measure airborne fine particles, while VOC sensors respond to selected volatile organic compounds or gaseous pollution changes.
A general VOC sensor should not be treated as an equivalent substitute for dedicated formaldehyde concentration measurement. Use an HCHO-specific sensor when that parameter is required.
Dedicated sensors provide flexible parameter selection and placement, while multi-in-one modules can simplify mechanical design and module integration. The right choice depends on measurement and hardware requirements.
No. The standard Winsen ZPHS01C module is offered in an HCHO version or a VOC version. These are alternative configurations.
ZPHS01B includes CO₂, particulate matter, formaldehyde, ozone, carbon monoxide, TVOC, nitrogen dioxide, temperature and humidity sensing functions. Refer to the official specifications for each measurement range and output unit.
Individual embedded sensor modules provide model-specific measurement outputs. Display, wireless communication, alarms and data storage are generally implemented by the finished device. Winsen WS-M1300 is a separate finished monitoring product with BLE functionality.
Important factors include representative air sampling, enclosure ventilation, power consumption, internal heat, sensor response characteristics, contamination, calibration and environmental limits.
