PM2.5 Kit
SKU:K023
Description
PM2.5 Kit is an air quality monitoring kit composed of a Basic controller, Module Air Quality with a built-in PMSA003 digital particulate matter concentration sensor, and Base BTC with a built-in SHT20 temperature and humidity sensor. It can simultaneously collect environmental particulate matter concentration and temperature/humidity data. The kit supports suspended particulate matter detection across multiple particle size ranges and can output mass concentration data related to PM2.5 standard values. It is suitable for real-time air quality monitoring, data logging, and trend analysis at fixed locations such as homes, offices, classrooms, and laboratories. It can also provide data reference for environmental improvement devices such as air purifiers and fresh air systems.
