Today, a team of researchers from the University of California have developed a low-cost, 3D-printed pollution sensor for detecting air contamination. This revolutionary device is designed to be used in many different applications, from monitoring air quality in homes to using it in cities for large-scale pollution detection. The device is made from a 3D-printed plastic frame and contains a sensor that measures the concentration of particulate matter. This particulate matter can be anything from dust to smoke to even small particles of pollutants. The device is also equipped with a simple interface for displaying the pollution levels and the ability to wirelessly transmit data. This is a huge breakthrough in air pollution monitoring and could make a big difference in how we detect and monitor air pollution.
