This vibrant nature sensor, called Feinstaubi, participates in the open source project Sensor.Community. The sensor measures the air temperature, humidity and the fine dust (PM 2.5 and PM 10). Inspired by the passion of Citizen Science, the artwork, disguised as passionfruit, is composed of glass beads that hide the temperature and humidity sensor inside the flower. The suction hose for the fine dust sensor is located on the exit of the canvas body, while the microcomputer (ESP8266) and the fine dust sensor are stored inside the canvas. The data is displayed on a LCD placed on the top of the installation.
