Integrate environmental measurements with AC controllers and optional functions.
Modern air conditioners increasingly combine temperature control with environmental monitoring and optional air treatment features. Sensor data allows manufacturers to provide more information about indoor conditions and develop additional smart AC functions.
Conventional split air conditioners primarily cool or heat and recirculate indoor air. By adding suitable environmental sensors, OEM manufacturers can extend the information available to the air conditioner controller and user interface.
These three capabilities are related, but they are not interchangeable.
Different AC product lines require different sensing functions. Temperature and humidity are common environmental parameters, while particulate matter, VOC, CO₂ and formaldehyde sensing can support selected advanced product features.

Start with the sensing and control functions required by the finished AC product. Then select the appropriate sensor modules based on dimensions, interfaces and equipment architecture.
| AC Product Type | Sensing Requirement | Suggested Winsen Products | OEM Consideration |
|---|---|---|---|
| Basic Split Air Conditioner | Temperature and humidity monitoring | ZS13A | Consider internal temperature gradients, sensor position and controller compatibility. |
| AC with PM Monitoring | PM1.0 / PM2.5 / PM10 measurement | ZH10-F | Evaluate sampling airflow, dust accumulation and humidity. |
| AC with Air Quality Level Display | General gaseous pollution grading | ZP07 | Suitable for 0–3 grade pollution indication, not selective concentration analysis. |
| AC with VOC & T&H Monitoring | VOC-related response, temperature, humidity | ZPS20 | Evaluate broad gas sensitivity, interference and environmental effects. |
| Compact Multi-Function Smart AC | PM2.5, VOC, temperature and humidity | ZH10-VHT | Integrated module reduces the need for separate sensing components. |
| Formaldehyde Monitoring AC | Dedicated HCHO measurement | ZE08K-CH2O | Use dedicated HCHO measurement rather than a general VOC signal. |
| AC with Fresh-Air Monitoring | CO₂ monitoring | MH-Z19E | A CO₂ sensor supplies data. Outdoor-air ventilation requires appropriate equipment. |
| Advanced Integrated IAQ AC | PM2.5, CO₂, T&H, HCHO or VOC | ZPHS01C | Confirm the HCHO or VOC configuration and mechanical integration. |
Integrating sensors into an air conditioner requires careful consideration of the actual indoor unit, control electronics, airflow and operating environment.
Sensor placement should reflect the intended monitored environment. Airflow near the AC unit may differ from general room conditions.
Indoor AC units may experience temperature gradients and high humidity. Avoid exposing sensors to condensation or conditions outside their rated limits.
Particle sensing depends on suitable air sampling. Consider dust accumulation, inlet obstruction and appropriate maintenance in the finished product.
Confirm working voltage, logic levels, communication protocols and connector design for each selected module.
The manufacturer defines measurement processing, air quality indicators, fan responses and optional smart control functions.
Verify sensor performance under realistic cooling, heating, fan speed and environmental conditions before mass production.
Winsen provides sensing modules for air conditioners and a broader range of indoor air quality, HVAC and smart air purification applications.
Common questions about PM2.5, VOC, CO₂, formaldehyde and environmental sensing in smart air conditioners.
Depending on product requirements, smart air conditioners may incorporate temperature, humidity, PM2.5, VOC-related air quality, CO₂ and formaldehyde sensors. Manufacturers select the appropriate combination according to the functions of the finished unit.
A PM2.5 sensor measures airborne particle concentration. The measurements may support an air quality display and compatible purification or control functions. The actual particle removal capability depends on the air conditioner's filtration or treatment hardware.
Some semiconductor gas sensors respond to selected gases associated with indoor odors and volatile organic compounds. They do not necessarily identify or quantify every odor-causing compound.
A CO₂ sensor provides carbon dioxide concentration measurements that may inform ventilation-related functions. A conventional recirculating air conditioner does not introduce outdoor air solely because it contains a CO₂ sensor.
No, not when dedicated formaldehyde concentration measurement is required. Broad VOC sensing and electrochemical HCHO sensing have different measurement characteristics.
ZH10-F focuses on particle measurements including PM1.0, PM2.5 and PM10. ZH10-VHT combines PM2.5, VOC, temperature and humidity functions within an integrated module.
No. Standard ZPHS01C modules are configured with either HCHO sensing or VOC sensing. These functions are not simultaneous in the same standard version.
The appropriate location depends on the monitored parameter, airflow, enclosure, heat sources and moisture conditions. Final positioning must be verified by the air conditioner manufacturer.
