Description
The H101-CO2-Z8S-U-40kP CO₂ gas sensor, hereinafter referred to as the PAS sensor, is a compact sensor with a wide measurement range. Employing the photoacoustic principle, it effectively detects CO₂ in the air. The sensor features excellent selectivity, operates independently of oxygen, and has an extended lifespan. With built-in temperature and humidity compensation, it offers enhanced usability. The PAS sensor represents a high-performance design, integrating photoacoustic spectroscopy detection technology with sophisticated circuit design and advanced algorithms. Its dimensions measure 20x15x7.8mm, making it suitable for space - constrained applications.
Application
- Automotive Air Conditioning Systems: Enables precise control of cabin air quality by monitoring CO₂ levels.
- Air Purification Devices: Facilitates efficient purification by detecting CO₂ concentrations and triggering purification mechanisms.
- Air Quality Monitoring Equipment: Plays a crucial role in providing accurate CO₂ data for comprehensive air quality assessment.
- Smart Homes: Allows for intelligent control of home environments based on CO₂ levels, enhancing comfort.
- Fresh Air Systems: Helps regulate the intake of fresh air by sensing indoor CO₂ levels.
Features
- Wide Range: Offers a measurement range of 400 - 5000 ppm, extendable up to 40000 ppm.
- High Sensitivity: Capable of detecting even minute changes in CO₂ concentrations.
- Stability: Demonstrates excellent long - term stability.
- Compensation and Output: Features temperature and humidity compensation, ensuring a linear output.
- Output Interface: Provides a UART (TTL 3.3V) output interface for easy integration.
- Long Lifespan: Has a lifespan of over 10 years.
- Resistance: Resistant to water vapor interference and immune to poisoning.

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.
