Those interested in monitoring the air quality in their locality may be interested in the new Raspberry Pi powered indoor air quality monitor project which has been created by Daniel Mancuso and kindly published to the Hackster.io website this week.
Using a USB air-quality sensor dongle to quickly mount an indoor air monitoring system, the Raspberry Pi 3 model B is capable of monitoring VOCs, Volatile organic compounds that are emitted as gases from certain solids or liquids.”VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands.”
The project will teach you how to quickly measure VOC levels using a USB sensor dongle connected to a Raspberry Pi, as well as store the data into an InfluxDB time-series database and use the Grafana application to quickly build an air-quality monitoring dashboard. “OhmTech’s uThing::VOC USB air-quality sensor dongle provides a quick way of obtaining data from the Bosch Sensortec BME680 sensor module.”
