Compact ESP32-S3 based air quality sensor uses an LED dial to tell how clean your air is (Crowdfunding)
If you are curious about the air quality in your area, then Studio LUFF Air Quality Sensor might be just the thing for you. It is designed to be affordable, open-source, portable, and customizable. Studio LUFF is a design practice based in California, United States composed of Pierluigi Dalla Rosa and two others. Collectively, they “advocate for an alternative approach to technology that is driven by curiosity, creativity, community and sustainability.” The Air Quality Sensor is their first product. The Air Quality Sensor is powered by an ESP32-S3 microcontroller and uses a Plantower PMS7003 particulate matter sensor module to measure air quality. It looks like a small, black disk with AQI (air quality index) values that run from 0 to 200. An LED dial is mounted on the back of the device which reflects on the wall to display the current air quality index in the area. The project was inspired […]
