Circuit to detect white ants

摘要

One of Australia's biggest but smallest pests is the white ant.Rarely seen,but highly destructive.A proud and meticulous homeowner may not even notice the first hint of their activity.What they need is a monitoring system or even a small handheld device that could be used like a stethoscope.Touch the target area with a microphone probe attached to a finely tuned and filtered amplifier,and listen for the sound of your house being devoured by thousands of tiny teeth.(P.S.,Whitsunday,Qld).
