Abstract There is increasing demand for low-cost dust sensors for air quality monitoring applications. The Shinyei PPD24NS is one to the most used devices but there is few work that establishes its performance conditions and characteristics. Consequently, its use has produced mixed results in terms of accuracy, precision and repeatability especially when they are employed while in motion. Our work aims at filling this gap by providing insight on the sensor operation, its limitations, the influence of air flow and noise sources. This work presents a guideline on supply voltage filtering, assembly and data treatment, aimed to improve the sensors’ shortcomings for future applications.
