ZE808-C8H8 Malodorous Gases Sensor Module uses high-precision electrochemical sensors,specialized instrument amplifiers, high-precision processors, and intelligent algorithms to convert the detected C8H8 gas concentration into recognizable digital signals, which are transmitted through serial ports. Convenient for users to use and debug, shortening their design and development cycle.
The module is equipped with sensors with good linearity, high precision, high sensitivity, strong anti-interference ability, excellent repeatability and stability, and combined with temperature and humidity compensation algorithms, greatly improving the reliability of the module.


Mainly used in gas monitoring, Internet of Things, UAV, atmospheric environment monitoring instrument, micro air quality monitoring station, toxic gas detection and other fields.


  • Small size
  • Dual signal output (UART signal, analog voltage signal)
  • High stability, high anti-interference
  • Temperature and humidity compensation
  • Sampling method can be selected: natural diffusion or integrated pumping

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
