Solar-Powered Sensors to Measure Air Quality in Baltimore
A team of scientists and nonprofit workers are gearing up to deploy 250 solar-powered sensors across Baltimore neighborhoods to measure dangerous pollutants like nitrogen dioxide. The plastic, toaster-sized cubes, designed by engineers at Johns Hopkins University and built with the help of Baltimore’s own residents through the nonprofit Civic Works, will hopefully help researchers better understand how smog levels differ from neighborhood to neighborhood — and even block to block — and in turn improve policymakers’ ability to address public health crises — like the city’s dangerously high asthma rate — with greater precision. The team hopes the sensors will create a “map” of air quality that allows researchers to better determine exactly why certain blocks are “smoggier” than others. If successful, the project could be replicated in other cities, as air-quality-related deaths are even worse in places like Los Angeles and Riverside, California. Click here to read more.
