DSM501B Dust Sensor Module (Air Quality Monitor)
The DSM501B Dust Sensor Module supplied by Week Technology Ltd. is designed to measure indoor airborne particles and pollen for air‑quality monitoring applications. It operates from a 5 V DC supply and draws a steady 90 mA current, allowing direct connection to low‑power controllers. The module outputs a PWM signal whose duty cycle corresponds to particle concentration, and it fits a compact 59 mm × 45 mm × 20 mm enclosure. The sensor can detect particles as small as approximately 1 µm, with a measurable concentration range from 0 to 1.4 mg/m³.
The device uses a 2.5 mm pitch connector (type s5b‑eh) and is rated for temperatures between - 10 °C and +65 °C, with relative humidity up to 95 % provided condensation is avoided. Typical dust‑sensor units maintain performance within defined upper and lower limits, and the DSM501B stabilises its readings after about one minute of power‑on. Industry practice classifies similar optical dust sensors as having a detection accuracy of ±10 % under standard conditions, and they are often housed in anti‑static packaging for protection during transport.
Customers such as air‑purifier manufacturers, HVAC system integrators and indoor‑environment monitoring firms use this module to drive fan speed control or to feed real‑time data to IoT dashboards. Week Technology Ltd. offers the module as a single‑unit or bulk pack, but exact MOQ, price and Incoterms must be confirmed directly with the supplier. The supplier’s address is 16 Floor, Building #3, Zhongke Mansion, Shenzhen 518067, Guangdong, China, and the company is listed as an imported tier with a harbour trust rating. Importers should verify the supplier’s response capability and request a compliance test report before finalising the purchase.

Sourcing DSM501B Dust Sensor Module (Air Quality Monitor) from Week Technology Ltd. - China Import Guide
Before placing an order, importers should confirm the exact corporate registration of Week Technology Ltd., verify the Shenzhen address against official business records, and request a sample unit or a test report demonstrating compliance with the listed electrical specifications. Checking the harbour trust tier and the supplier’s response history can help gauge communication reliability, while a written agreement should specify any required certifications such as CE or RoHS, even if they are not listed in the catalogue.
Logistics for the DSM501B typically involve sea freight to major Chinese ports followed by inland transport to the buyer’s warehouse. Buyers need to agree on Incoterms - commonly FOB Shenzhen or CIF destination - and confirm payment terms, which are often 30 % advance with the balance on document presentation. Lead‑time estimates should be obtained from the supplier, as they can vary with production scheduling and customs clearance procedures.
Quality assurance should include a pre‑shipment inspection of the PWM output accuracy, power consumption and dimensional tolerances against the data sheet. Importers are advised to arrange an independent third‑party test lab to verify particle‑size detection limits and to obtain a calibration certificate. Documentation such as a test report, conformity declaration and packing list must be reviewed before the goods are released at the port.
