Mapbox provides the PurpleAir map interface.Įach PurpleAir sensor includes a BME280 pressure, temperature, and humidity sensor. Google App Engine provides the processing power to place the sensor icons on the PurpleAir map and create the graphs and other elements to display sensor data on the PurpleAir map. Google maps provides the map interface for sensor registration. Using services from Google makes for a robust, reliable, and secure system.
PurpleAir uses HighCharts and data stored on ThingSpeak to create graphs on the PurpleAir map. ThingSpeak provides the cloud storage for PurpleAir sensor data. Each PurpleAir air quality sensor device checks for updates from time to time.
#PARTICLE ILLUSION 3.0 SHOCKWAVE SMOKE UPDATE#
PurpleAir firmware has remote update features, meaning we can modify the software and the sensor will download the new version and update itself. PurpleAir sensors use an ESP8266 chip to talk to the particle counter and provide all functionality, including connecting to a WiFi network and uploading data to the cloud. So far, all sensors we tested have produced consistent output using laser particle counters. PMS5003 and PMS1003 sensors come factory calibrated.īefore deploying any devices, we verify that they are giving out readings that are consistent from sensor to sensor during tests in a smoke chamber. These particle counts are processed by the sensor using a complex algorithm to calculate the PM1.0, PM2.5, and PM10 mass concentration in ug/m3. These sensors count suspended particles in sizes of 0.3, 0.5, 1.0, 2.5, 5.0, and 10um. PurpleAir uses PMS5003 and PMS1003 laser particle counters. PurpleAir sensors are an "Internet of things" (IOT) air quality sensor or particulate sensor consisting of a network of elements
