PrintAirPipe - 125 Air Sensor Segment - 3D Printable - STL Files


Categories: , ,


With the help of the PrintAirPipe - 125 Air Sensor Segment for the PrintAirPipe System it is possible to measure various properties of the air around the pipe system.

For this purpose, a BME680, a BME280 and one of the available Fermion gas sensors from DF-Robot be installed.

The sensors can then be read out using the SeeedStudio XIAO ESP32 S3 built into the sensor segment. Thanks to the firmware based on the ESPHome framework, the data can easily be forwarded to a SmartHome system or elsewhere and processed accordingly. 

This also makes it possible to react to certain values. For example, the supply air path can be shut off after a certain change in air quality has been detected. For this purpose, the PrintAirPipe - ServoValve be used.
