Import Cozir-W Ultra Low Power Ndir Co2 Sensor — Buy in wholesale FOB from Supplier in China

The Cozir-w Ultra Low Power NDIR CO2 Sensor is a third-generation infrared sensor designed for battery-powered and portable applications, measuring carbon dioxide concentrations from 0% to 100% VOL. It operates at a supply voltage of 3.3V with a peak current draw of 33mA and consumes only 3.5mW during active measurement, making it suitable for long-duration deployments in IoT devices and HVAC systems. The sensor uses GSS IR LED and detector technology with an optimized optical path to ensure stable readings without drift.

This sensor supports optional integrated temperature and humidity output, though these features cannot be enabled simultaneously with analog output. The output interface is configurable as either analog voltage or digital UART, allowing flexibility in system integration. Typical industry applications require a response time under 3 seconds and operating temperatures between 0°C and 50°C, which this model meets without external calibration. The housing is sealed to protect internal optics from dust and condensation, a standard requirement in environmental monitoring equipment.

End users include manufacturers of indoor air quality monitors, smart thermostats, demand-controlled ventilation systems, and portable safety devices. Buyers typically source this sensor in volumes of 500 units or more for OEM integration. Packaging is in anti-static trays with individual foam inserts. Trade terms are FOB Shenzhen, with lead times of 2 to 4 weeks depending on order size. Certification documentation such as RoHS and CE is available upon request but not pre-confirmed on this listing.

Week Technology Ltd. is a supplier based in Shenzhen, Guangdong, with a physical address listed at 16 Floor, Building #3, Zhongke Mansion. The company is classified as an imported supplier with harbor trust tier, indicating verified business registration and physical presence. There is no public information on years of operation, team size, or export history. The listing confirms active product development in gas sensing technology but provides no details on internal testing facilities or R&D staff.

This supplier does not publish certifications, client lists, or production capacity figures. The absence of response rate or average reply time suggests limited customer service infrastructure. Buyers should treat this as a product-focused manufacturer without established after-sales channels. All claims about sensor performance are derived from the product datasheet and not independently verified by the supplier profile.
