which is particle concentration distribution, and then converts to mass concentration. At the same time, a temperature & humidity integrated sensing chip is embedded in the module for accurately detecting the temperature and humidity.
This air quality sensor combines the particle concentration value, temperature, and humidity monitoring functions onto one module, and outputs the relevant data frames via UART. It can be embedded in various instruments and equipment related to air quality monitoring and environmental air improvement to provide timely and accurate environmental parameters.
