Pop-Up Particle Pavilion Part 2: The Build & Demo

In this article, I attempt to explain how I built my particle pavilion. I will use a combination of words, photos & videos to demonstrate how sensors can monitor internal air quality and activate motorised shutter walls, servo-assisted sliding skylights, embedded warning lights & automatic fans to improve the user experience of shared spaces. Hopefully, you’ll get an insight into how I used the following components to realise my particle pavilion idea:

• Adafruit ESP32-S2 Feather with BME280 Sensor
• Adafruit Stepper Motor Featherwing
• Adafruit TFT FeatherWing - 2.4" 320x240 Touchscreen For All Feathers
• Adafruit SCD 40 - True CO2, Temperature and Humidity Sensor
• Mini Stepper Motor - 200 Steps - 20x30mm NEMA-8 Size (2 off)
• Micro 360 Degree Continuous Rotation Servo FS90R
• Linear actuator
• 5V DC, Axial Fan, 40 x 40 x 10mm, 7CFM
• Relay - 5V
• Kitronik ZIP Stick - 5 ZIP LED
• 4mm Economy Birch Laser Plywood - 600mm x 400mm
• sheet Clear Perspex Sheet (Cast) 4mm x 600mm x 400mm Lipo Battery - 3.7 v; 500mAh
• AA Battery pack; 3x 1.5V
• Jumper wires
• USB C to B Cable
• M3 button head screws
• M3 hex nuts

In one of the videos, you’ll able be to see the DesignSpark air quality monitor keeping tabs on the external air quality while the pavilion’s internal sensor monitors & then triggers various reactions to co2 levels from inside.

Next - Part 3

In part 3, I will be sharing the following:

• The files for all the laser cuts components
• The Code
• The Data Visualisation on Adafruit Io (IoT)
• More detailed wiring diagrams/guidance
• My reflections
