No, NASA did not invent smoke detectors. Smoke detectors were actually invented by George Andrew Darby in 1902. NASA has, however, improved smoke detectors for use in spacecraft and space stations.
The first practical electric smoke detector was invented by the American physicist George Andrew Darby in 1965. However, the concept of using ionization to detect smoke dates back to the 1930s.

The first battery-operated smoke detector was invented in 1965 by George A. Darby, which significantly improved home safety by allowing detectors to be installed without the need for electrical wiring. This innovation paved the way for widespread adoption of smoke detectors in homes, enhancing fire safety measures. The technology has since evolved, but Darby’s invention marked a crucial turning point in fire prevention.
