PurpleAir - Model PA-II -Laser Pollution Sensor
The PurpleAir PA-II is an air quality sensor that measures real-time PM2.5 concentrations for residential, commercial, or industrial use. Built-in WiFi enables the air quality measurement device to transmit data to the PurpleAir map, where it is stored and made available to any smart device. The PA-II is available in two editions. The SD edition includes an onboard SD logger to record and store data without a WiFi connection. The power option includes a specialized, high-quality outdoor (IP68 rated) USB power supply with 17 feet of cable to safely power your sensor outdoors.
