🔘 Until now the atmospheric "Particulate Matter Detector ( PMD )" project based on a 🪴Plantower 🗼PMS5003 particle concentration sensor and having a ⎚ display had been assembled on a solder-less 🍞 breadboard, ( see 📅16 June 2024 ), while awaiting further development.
A 'U ' cross-section 🖼frame, which functions as a stand, has been designed and produced on a 3-D printer 🖶 so that the PMD ( comprising PMS5003, colour display & µ-controller ) is now self-contained and can be easily moved to different locations.

Being open construction the micro-usb connector for power and serial data, ( requiring the 'PMD_Serial' software ), reset & boot buttons and SD card slot on the rear of the display are easily accessible. An SD card could perhaps be used to load an image when the PMD starts, or for data storage.
The stand is very stable. The addition of rubber feet provides extra non-slip adhesion on smooth surfaces, as well as protection from scratches. Overall dimensions are 122 x 70 x 64mm.
PMS5003 sensor is the blue module with fan air inlet.
