Calibration of SPS30 Particulate Matter Sensor Using Feedforward Neural Networks
摘要
Devices available on the market to measure particulate matter are too expensive to deploy them with high spatial resolution. In this paper we present a particulate matter measurement device, which is based on the low-cost SPS30 sensor. We show that using a feedforward neural network running on a Raspberry Pi 4, which also considers the ambient temperature and humidity, the measurement results can be calibrated to the ones like the cost-intensive particulate matter measurement device Fidas 200 E for a defined population of particles. We show that after the calibration the measurement results of our low-cost device are comparable to the ones of the cost-intensive device in a comparable particle population. We conclude that the use of feedforward neural networks allows the usage of low-cost particulate matter measurement devices to archive high spatial resolution when monitoring particulate matter concentrations.
