Description
MH-T4041A low-power infrared gas sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as the sensor), using non-dispersive infrared (NDIR) principle to detect hydrocarbon combustible gases in the air. It has good selectivity, ultra-low power consumption, no oxygen dependence, stable performance, long life, and built-in temperature compensation.The sensor is a compact and high performance sensor which combines the mature infrared absorption gas detection technology with micro-machining and excellent circuit design. It is easy to use, can directly replace catalytic combustion elements, so it is widely used in various occasions where combustible and explosive gases exist.
Application
- HVAC Refrigeration and Indoor Air Quality monitoring
- Industrial Process and safety protection monitoring
- Agricultural and animal husbandry production process monitoring
Features
- High sensitivity, high resolution, fast response time, ultra-low power consumption
- Provides a variety of output modes, such as UART and analog voltage
- Temperature compensation, excellent linear output, excellent stability, long service life
- Anti-water vapor interference, no poisoning, can directly replace the catalytic combustion principle sensor

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, but the module will be 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 sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
