Abstract  Due to the small size, low requirements for electric drive and real-time monitoring performance, low-cost particulate matter sensors greatly reduce the cost of environmental air grid monitoring, which has a huge application prospect. Although the cost is reduced, the output of the particle sensor is affected by many factors. Many previous studies investigated the influence of particle properties, environmental conditions on the performance of particle sensors, as well as the output quality of particle sensors in long-term operation. At present, lack of relevant standards about the quality, detection parameters and methods of low-cost particle sensors resulting in the problem on comparability and uniformity. To promote the quality and provide a scientific measuring system of low-cost particle sensors, the factors influencing the performance of low-cost particle sensors in previous studies were reviewed.
