MicroSD Card

PurpleAir Verified independent store

This MicroSD card is compatible with PurpleAir monitors that support local data storage, including the Classic-SD, Flex, and Zen models. With ample storage capacity, this card can hold over two years' worth of air quality data under normal usage. For best results, we recommend periodically checking to ensure data is being recorded properly. Using SD data storage enables offline data collection. SD logs are not uploaded to the cloud by the PurpleAir sensor. If the sensor is connected to WiFi with an SD card present, data will be logged to the SD card and sent to the cloud. Show more
