Abstract:
A method for detecting insect infestation in stored products comprising:(a) placing a grain probe detector containing (1) a sensor head having at least one transducer for detecting the passage of at least one insect through the probe sensor head, and (2) a circuit board operatively connected to said transducers; into a stored product, (b) detecting the passage of at least one insect through the probe and providing an analog output, and generating a signal present digital pulse in said circuit board based on said analog output, (c) determining if said signal is greater than threshold level, (d) sending said signal greater than threshold level to a microcontroller on said circuit board, (e) processing said signal to extract data from said signal, and (f) storing said signal process in a memory of said microcontroller.
