This module integrates mature VOC detection technology and advanced PM2.5 detection technology to detect VOC and PM2.5 at the same time. The VOC sensor in this module has high sensitivity to formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol, cigarette smoke, essence and other organic vapors.PM2.5 detection adopts particle counting principle to detect the particles (diameter ≥1μm).
Before delivery, the sensor has been aged, debuged, calibrated and has good consistency and high sensitivity. It has the PWM signal output, and it can be configured to be UART digital serial interface and customized IIC interface.


Air refresher, air conditioner, ventilating device, monitor equipment for environment, smoke alarm &etc.


High sensitivity, good stability for long time, calibrated before delivery, built-in heater to snift air automatically. It has the the advantages such as small size, light weight, easy to install and use, simple maintenance &etc.

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
