SnifferStar™ is a micro chemical analysis system developed jointly by Sandia National Laboratories and Lockheed Martin (under Lockheed Martin's Shared Vision program) for deployment on Unmanned Aerial Vehicles (UAVs). As the UAV moves through the air, it collects a sample and performs a rapid analysis for chemical warfare agents. The UAV / SnifferStar™ provides a mobile chemical detection platform that can be used on either a military battlefield or in civilian applications, and serves as an early warning indicator of chemical warfare attack. The entire module weighs less than 16 grams and operates on half a watt of power.

| SnifferSTAR Device |
SnifferSTAR™ consists of two microfabricated components, a preconcentrator and a saw detector array contained in a fluid manifold, atop a microprocessor board smaller than a credit card. The forward motion of the vehicle forces air through the device. Material in the sampled air is absorbed and concentrated. It is then thermally released desorbed). The mass of incoming particles changes the frequencies. The altered frequency data are passed to a processing unit on the SnifferStar™ module. The data are then relayed to a processor on the drone or radio-linked to a main data processor on the ground. The information is automatically compared against a library of the patterns created by a range of gases. The sampling process is repeated every 20 seconds, with 15 seconds intake and five seconds for analysis. The inrush of air then clears the device sensors for the next reading.
