These droplets exploit ammonia\u2019s affinity for water to rapidly capture NH\u2083 when it is present.<\/p>\n<p>When an ammonia-laden droplet falls onto the sensor, its mechanical impact completes an electrical circuit, generating signals that are converted into accurate gas measurements at a speed that exceeds existing ammonia gas sensors.<\/p>\n<p>To take detection precision a step further, the team integrated an AI model that analyzes electrical signals and converts them into time-frequency images. After training on these images, the system classified ammonia into five concentration levels (0\u2013200 ppm), achieving up to 98.4% detection accuracy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers from Guangxi University, China have developed a new gas sensor that detects ammonia with a record speed of 1.4 seconds.
