Description
The MH-Z1341B combustible gas sensor (hereinafter referred to as the sensor) is a universal and compact sensor that uses the principle of non dispersive infrared (NDIR) to detect combustible gases in the air. It has good selectivity, no oxygen dependence, long lifespan, built-in temperature compensation, digital output, and is convenient to use. This sensor is a high-performance sensor that combines mature infrared absorption gas detection technology with precision optical path design and sophisticated circuit design.
Application
- Residential gas leak alarms
- HVAC equipment
Features
- The air chamber is treated with electroplating, waterproof and corrosion-resistant
- High sensitivity, low power consumption
- Excellent stability
- Temperature compensation, excellent linear output
- Provide UART output mode
- Long life-span
- Anti moisture interference, anti-poisoning
- Anti interference from acetic acid and ethanol

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
