Arduino CO2 Sensor v.1
Description
I Have Printed The Case In Pla With My Prusa I3 X. The Mq135 (Air-Quality Sensor) Is Controlled By An Arduino Nano And Connected With A Hc-06 Bluetooth Module To Interact With An Android Smartphone (And See The Ppm Level). The Magnets Hold The Face To The Case. A Yellow Led Will Switch On When The Sensor Detects 1000 Ppm And A Red Led Will Switch On When It Detects 1500 Ppm. I Have Decided To Construct This Sensor In Particular For Schools. Infact, I Have Noticed That The Level Of Attention Decreases With A High Co2 Level. I Hope You Can Find This Sensor Useful!
