The air purifier that was using the PM sensor had a different connection port, so this item didn’t work. Just double check that before you go purchasing this. Review: Works! Easy to connect - The device works great. It connects to your microprocessor via UART. Several libraries available on GitHub so easy to use on Arduino or Raspberry PI. I used an ESP32 to test the unit and it worked well. Unit able to detect all sorts of particles. Smoke, mist, powder, etc.... ## Features - √ [Accurate Measurement] -- The scattering principle enables accurate measurement and reduces errors. - √ [Control System] -- Constant wind pressure and flow adaptive control system. - √ [Performance Stable] -- The optical system uses high-performance modules and light-sensitive components to make the operation stable. - √[Optimization Compensation]--The depth algorithm is used to optimize the compensation to ensure stable and consistent measurement results in different environments. - √ [Excellent design] -- The same side air inlet and outlet simplifies the structural design and dustproof sensor structure design. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07S3735CY | | Best Sellers Rank | #696,244 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #940 in Indoor Air Quality Meters | | Date First Available | May 22, 2019 | | Item Weight | 0.317 ounces | | Item model number | Keenso1e8bhfxci4 | | Manufacturer | Keenso | | Product Dimensions | 0.39 x 0.39 x 0.39 inches | ## Images ![PM2.5 Sensor - Image 1](https://m.media-amazon.com/images/I/415t+ZjdzoL.jpg) ![PM2.5 Sensor - Image 2](https://m.media-amazon.com/images/I/41AtdZeInNL.jpg) ![PM2.5 Sensor - Image 3](https://m.media-amazon.com/images/I/41O-Yb-EwzL.jpg) ![PM2.5 Sensor - Image 4](https://m.media-amazon.com/images/I/41nBpSGd4oL.jpg) ![PM2.5 Sensor - Image 5](https://m.media-amazon.com/images/I/41oPRyxSslL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Didn’t Fit My Connector *by M***M on February 26, 2024* I think this is a very capable PM sensor, just make sure it fits into the connector that you have on your machine .
