In this way, the scattering of light is generated by laser irradiation on suspended particles in the air, and the scattering light is collected at a certain Angle, and the curve of the scattering light intensity changes with the time is obtained. Then the microprocessor uses the algorithm based on MIE theory to get the equivalent particle size and the number of particles with different particle sizes in unit volume. - ♥Sensor Specifications:✔Particle measurement range: 0.3~1.0; 1.0~2.5; 2.5~10 microns (μm)✔Particulate mass concentration resolution: 1 μg/m3✔Single response time: <1 second (s)✔Comprehensive response time: ≤10 seconds (s)✔DC supply voltage: Type: 5.0 Min: 4.5 Max: 5.5 Volts (V)✔Working current: ≤100 mA (mA)✔Standby current: ≤200 microamps (μA)✔Operating temperature range: -10~+60 degrees Celsius (°C)✔Working humidity range: 0~99%✔Storage temperature range: -40~+80 degrees Celsius (°C) - ♥ WHAT YOU GET: The package includes 1pcs PMS5003 Digital Particle Concentration Laser Sensor ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | EC Buying | | Part number | EC Buying PMS5003 | | Item Weight | 41 g | | Package Dimensions | 14.5 x 10.49 x 2.21 cm; 41 g | | Manufacturer reference | EC Buying PMS5003 | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Brand:** EC Buying - **Maximum Supply Voltage:** 5.5 Volts - **Measurement Accuracy:** ±1% - **Measuring Range:** 0.3~1.0 μm, 1.0~2.5 μm, 2.5~10 μm - **Style:** Modern ## Images ![PMS5003 Digital Particle Concentration Laser Sensor/High Precision Laser Sensor to Detect Air Quality Suitable for Smart Home - Image 1](https://m.media-amazon.com/images/I/61PGnB4zZiL.jpg) ## Frequently Bought Together - EC Buying PMS5003 Digital Particle Concentration Laser Sensor/High Precision Laser Sensor to Detect Air Quality Suitable for Smart Home - Ximimark 3Pcs MQ135 MQ-135 Air Quality Sensor Hazardous Gas Detection Module for Arduino - HiLetgo 2pcs DHT22/AM2302 Digital Temperature And Humidity Sensor Module Temperature Humidity Monitor Sensor Replace SHT11 SHT15 for Arduino Electronic Practice DIY --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/526738870-pms5003-digital-particle-concentration-laser-sensor-high-precision-laser-sensor](https://www.desertcart.co.th/products/526738870-pms5003-digital-particle-concentration-laser-sensor-high-precision-laser-sensor) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-11*
