New pocket-sized sensor can detect a silent threat in the air

A new low-cost sensor can help detect toxic sulfur dioxide (SO2) gas responsible for respiratory irritation, asthma attacks, and long-term lung damage, at extremely low concentrations. SO2 is a toxic air pollutant commonly released from vehicles and industrial emissions, and even minute exposure can cause serious health issues and long-term lung damage. It is hard to detect before it has an adverse effect on health. Monitoring SO2 levels in real…
