The PM2.5 Air Quality Module is an ambient air quality testing module. This product has a PMSA003 digital universal particulate matter concentration sensor. It can collect and calculate the number of suspended particles of different particle sizes in the air per unit volume. The simple design makes enables it to quickly deploy nodes and be used in life or industrial scenarios. It can be used as environmental data collection, or providing real-time and accurate concentration data for instruments, or environmental improvement equipment related to the concentration of suspended particulate matter in the air.
