Co2 Sensor For Indoor Air Quality Control
The TGS4161 CO2 sensor from Week Technology Ltd. is a non-dispersive infrared (NDIR) sensor designed for continuous monitoring of carbon dioxide concentrations in enclosed environments. It operates within a measurement range of 400 to 5000 ppm with a typical accuracy of ±50 ppm or ±5% of reading, whichever is greater. The sensor has a response time under 120 seconds and requires a 5V DC power supply with a maximum current draw of 80 mA.
This sensor uses a solid-state infrared source and detector pair with optical filtering to isolate the 4.26 µm absorption band of CO2, minimizing interference from water vapor and other gases. The housing is sealed to IP54 standards, allowing operation in humid indoor conditions without internal condensation. It is typically mounted in wall-mounted air quality monitors, HVAC control units, or smart building systems. The sensor output is analog 0.5 to 4.5 V or digital PWM, compatible with most embedded controllers.
Buyers commonly deploy this sensor in offices, classrooms, and healthcare facilities where occupancy-driven CO2 buildup affects cognitive performance and comfort. It is integrated into systems that trigger ventilation when levels exceed 800 ppm. Minimum order quantities are flexible and negotiated directly with the supplier. Packaging is anti-static, with individual units in foam-lined boxes. Shipping is typically FOB Shenzhen, with lead times of 10 to 15 working days after confirmation.

Sourcing Co2 Sensor For Indoor Air Quality Control from Week Technology Ltd. - China Import Guide
Before ordering, verify the exact sensor model number and firmware version, as variations exist within the TGS4161 family. Request a copy of the calibration certificate and a test report showing performance at 1000 ppm and 4000 ppm CO2. Confirm the output signal format matches your controller’s input requirements, and ask for a pinout diagram and wiring schematic. Do not assume compatibility without written confirmation from the supplier.
Lead time is typically 10 to 15 working days after payment, but confirm this in writing. Shipping terms are usually FOB Shenzhen, and buyers should clarify whether insurance is included. Payment is commonly via T/T, with 30% deposit and 70% before shipment. Ask for a proforma invoice with HS code, net weight, and packaging dimensions. Ensure the supplier provides an export declaration and commercial invoice in English.
On delivery, inspect for physical damage and verify the sensor’s serial number against the packing list. Use a calibrated CO2 meter to test output against a known reference gas. Check for consistent signal response over 30 minutes. Retain a sample unit for quality reference. Request a batch test report and a certificate of conformity. If used in regulated environments, ensure documentation supports compliance with local indoor air quality standards such as ASHRAE 62.1 or EN 13779.
