Import Carbon Dioxide (Co2) Sensor Module Cdm7160 — Buy in wholesale FOB from Supplier in China

The Carbon Dioxide (CO2) Sensor Module CDM7160 from Week Technology Ltd. is a compact NDIR (Non-Dispersive Infrared) device designed for precise CO2 concentration monitoring. It features a detection range typically spanning 0 to 5000 ppm, with an accuracy of ±30 ppm or ±3% of reading, whichever is higher, ensuring reliable data for environmental assessments. The module operates at 3.3V or 5V DC with a power consumption below 50 mW, making it suitable for battery-powered applications.

Housed in a robust plastic enclosure, the CDM7160 integrates a dual-wavelength infrared source and detector pair, a standard configuration for NDIR sensors to minimise cross-sensitivity to humidity or temperature fluctuations. The sensor’s response time is typically under 30 seconds for 90% of the final reading, a critical feature for real-time air quality systems. Typical industry specifications for such modules include an operating temperature range of -10°C to 50°C and a storage range of -20°C to 60°C, with humidity tolerance up to 95% RH non-condensing.

This sensor is widely adopted in HVAC systems, smart buildings, and agricultural environments like greenhouses where CO2 levels directly impact plant growth and human comfort. Importers sourcing from Week Technology Ltd. should confirm compatibility with their control systems, as the module supports UART, I2C, and PWM output interfaces. The unit’s compact dimensions, typically around 30 mm x 20 mm x 10 mm, allow for seamless integration into existing setups, while its low drift over time reduces the need for frequent recalibration.

Week Technology Ltd. is based in Shenzhen, Guangdong, China, with its office located at 16 Floor, Building #3, Zhongke Mansion. The company operates as an importer-tier supplier, specialising in sensor modules and electronic components for industrial and environmental applications. Its profile indicates a focus on providing technical hardware solutions, though its response rate and average response time are currently unrecorded, which may require direct outreach for timely inquiries.

The supplier’s trust tier is categorised as harbor, reflecting a baseline level of verification within the sourcing ecosystem. While the company does not explicitly state certifications or production capacity in its profile, its product offerings, such as the CDM7160 CO2 sensor module, suggest a commitment to niche electronic components. Buyers should verify the supplier’s ability to meet specific volume, lead time, and technical support requirements before finalising orders.
