New DANGER - Flying cannabis sniffing drones

[ANC]

The unmanned mini-helicopter has been dubbed the "Canna Chopper," and has been put to use sniffing out illegal grow operations in the Netherlands. Apparently only 10% of Dutch-grown pot is legal. Who knew?
The Canna Chopper boasts odor and video sensors to find pot fields from the air, and on its first trip it rounded up seven outlaw farmers and several kilos of product, so looks like it's reasonably effective. Effective at being no fun.

odor detection? i had no idea. =/

Odor sensor is combination of a sensitive layer and a transducer. Nanocrystalline ITO thin film deposited over quartz crystal works as a sensitive layer, while quartz crystal works as a transducer. During operation of odor sensor, ITO layer sense the presence of test odor molecules, hence the totals mass on its surface will change, while the quartz crystal transducer converts the change in the mass into the change in the frequency. So the basic principle of operation of sensor is change in the frequency by change in concentration of odor or vapor molecules.

Shoot da motherfucking thing !!!!!!

I wonder how sensitive the system is and if they were targeting outdoor/indoor growers.
