Import Dl0001 Laser Dust Sensor — Buy in wholesale FOB from Supplier in China

The DL0001 Laser Dust Sensor is a compact optical detector that quantifies airborne particle concentration, including PM2.5, by analysing light scattering. It measures particles in three size bands - 0.3‑1.0 µm, 1.0‑2.5 µm and 2.5‑10 µm - providing an effective mass concentration range of 0‑500 µg/m³ and a maximum measurable limit of 999 µg/m³. The sensor delivers a resolution of 1 µg/m³ and reports data through a universal digital interface powered by a 5.0 V DC supply drawing 100 mA. Its response time for a single measurement is 1 s, with a total system response of 10 s.

The device employs a lens‑less design that improves measurement consistency and eliminates calibration drift caused by optical components. Typical laser‑diode modules used in similar sensors operate at wavelengths around 905 nm and are rated for continuous operation up to 50 °C, which matches industry standards for indoor air‑quality equipment. The built‑in microprocessor performs real‑time conversion of photodetector current to mass concentration, a practice common in modern particulate monitors.

Applications include integration into ventilation systems, air purifiers, HVAC units, automotive cabin filtration and other home appliances that require continuous air‑quality monitoring. Importers targeting OEMs or system integrators should request the sensor’s communication protocol documentation and confirm compliance with CE or equivalent certifications. Trade terms such as minimum order quantity, FOB or CIF shipping and payment conditions must be negotiated directly with Week Technology Ltd. The supplier’s harbour trust tier indicates a verified commercial presence in China.

Week Technology Ltd. is an imported‑tier supplier based at 16 Floor, Building #3, Zhongke Mansion, Shenzhen, Guangdong, China (postal code 518067). The company holds a harbour trust tier, indicating third‑party verification of its business legitimacy. Its public response rate is currently 0 %, and average response time is not recorded, which suggests that communication may require proactive follow‑up. Week Technology Ltd. lists the DL0001 Laser Dust Sensor as part of its product catalogue for air‑quality monitoring solutions.

The supplier does not disclose additional corporate history, employee count or revenue figures, and it does not publish specific certifications on the listing. Buyers should request copies of any relevant quality or safety certificates, such as CE or ISO 9001, directly from the company before finalising a contract. Week Technology Ltd. offers the sensor for bulk purchase, but exact MOQ and pricing are not stated in the public data. All trade negotiations, including payment terms and shipping arrangements, must be arranged directly with the supplier.
