ZE730-CO is a general-purpose, miniaturized gas detection module. The module is equipped with a fuel cell type electrochemical button sensor, which not only has low power consumption, but also can effectively avoid the risk of leakage of traditional electrochemical sensors. In terms of circuit, the instrument amplifier, high-precision AD converter, etc., the detected gas concentration is converted into a digital signal, and the data transmission can be carried out through serial port, PWM and other signals, not only the signal is stable, but also a multiple choice.


Vehicle lithium battery failure detection, smart home CO gas detection, portable carbon monoxide detector, etc.


High temperature resistance, fast response, low power consumption, high precision, long life.

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
