Compared to official readings and it was accurate. Well worth the price. Review: Dead after second use - 0 output on all PPM values, it powers up with <10 on all values and drops to Zero. Overall Trash component. Will tinker with it a bit more, but i think this is 20$ wasted. ## Features - ♥PMS5003 is a digital universal particle concentration sensor based on the principle of laser scattering, which can continuously collect and calculate the number of suspended particles of different particle sizes in the air per unit volume, that is, the particle concentration distribution, and then convert it into mass concentration, and use the universal Digital interface form output. - ♥ Main features★Accurate measurement by laser scattering principle★Zero false alarm rate★Real-time response and support continuous acquisition★Minimum resolution particle size 0.3μm★New patented structure, all-round shielding on six sides, stronger anti-interference performance★ The direction of the air inlet and outlet is optional, the application range is wide, and the user does not need to design the air duct - ♥ Working principle:PMS5003 sensor adopts the principle of laser scattering. 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 | |---------------|-------| | ASIN | B0B38J2836 | | Best Sellers Rank | #117,013 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #158 in Indoor Air Quality Meters | | Brand | EC Buying | | Date First Available | June 6, 2022 | | Item Weight | 1.44 ounces | | Item model number | PMS5003 | | Manufacturer | 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 | | Output Type | Digital | | Package Dimensions | 5.71 x 4.13 x 0.87 inches | | Response Time | 1 seconds | | Specific Uses For Product | Concentration Sensor | | Style | Modern | | Upper Temperature Rating | 60 Degrees Celsius | ## 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) ## Customer Reviews ### ⭐⭐⭐⭐⭐ I have it running non stop in lab *by J***S on November 21, 2023* I really like it. Compared to official readings and it was accurate. Well worth the price. ### ⭐ Dead after second use *by R***S on January 24, 2026* 0 output on all PPM values, it powers up with <10 on all values and drops to Zero. Overall Trash component. Will tinker with it a bit more, but i think this is 20$ wasted. ### ⭐ Sensor Would Not Power Up *by A***C on September 24, 2025* DOA on arrival. Amazon did refund without me having to return it so the 1 star is for this product not for the Amazon response as it was fast and efficient. My plan was to use this with a Raspberry Pi 2W for in house air quality monitor. ## 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/457267332-pms5003-digital-particle-concentration-laser-sensor-high-precision-laser-sensor](https://www.desertcart.co.th/products/457267332-pms5003-digital-particle-concentration-laser-sensor-high-precision-laser-sensor) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
