DSM501B Dust Sensor for Air Quality Monitor
The DSM501B Dust Sensor for Air Quality Monitor is a compact module designed to detect indoor airborne particles and pollen. It operates from a 5 V DC supply with a tolerance of ±10 % and draws 90 mA of current. The sensor reports particle concentration via a PWM output and stabilises within one minute after power is applied. Physical dimensions are 59 mm × 45 mm × 20 mm and it uses a 2.5 mm pitch connector (S5B‑EH).
The detection limit is approximately 1 µm, with a measurable range from 0 to 1.4 mg · m⁻³, which aligns with typical photometric dust sensors used in indoor air quality equipment. Operating temperature is specified between - 10 °C and +65 °C and relative humidity up to 95 % without condensation, matching standard environmental sensor specifications. The module’s lightweight, low‑profile design is common in compact air‑handling devices where space is limited. Industry practice often pairs such sensors with microcontroller units that interpret PWM duty cycle to control fan speed or ventilation rates.
Typical applications include integration into ventilators, air‑conditioners, dedicated air‑quality monitors and portable air purifiers. Buyers should confirm the supplier’s minimum order quantity, lead time, and preferred Incoterms before placing a purchase. As the listing does not disclose pricing or certification details, direct contact with Week Technology Ltd. is required to obtain trade terms.

Sourcing DSM501B Dust Sensor for Air Quality Monitor from Week Technology Ltd. - China Import Guide
Before placing an order, importers should request the supplier’s test reports that confirm the sensor meets the stated electrical parameters and particle detection limits. It is advisable to ask for a datasheet that lists the calibration method, PWM duty‑cycle mapping and any certifications such as CE or RoHS, even though they are not shown in the listing. Verifying the exact connector type and dimensions against the buyer’s hardware design reduces integration risk.
Buyers need to clarify the expected production lead time and whether the supplier can ship under FOB Shenzhen, CIF, or another Incoterm that matches the buyer’s freight strategy. Payment terms are typically negotiated as a deposit against a pro‑forma invoice followed by balance on sight‑letter of credit, but the exact arrangement must be confirmed with Week Technology Ltd. Shipping volume and packaging dimensions should be discussed to obtain accurate freight quotes.
It is prudent to arrange a third‑party inspection at the factory before shipment to verify that the sensors conform to the specified performance criteria, such as PWM accuracy and power consumption. Importers should request an inspection report covering functional testing, visual inspection of the PCB and connector integrity, and verification of the supplied datasheet values. Additionally, obtaining a certificate of conformity and a test report from an accredited laboratory will help satisfy customs and end‑user requirements.
