Pest detection and monitoring probe in a grain storage bin

A system for detecting and monitoring pests in a grain storage bin, the system comprising:

• a probe comprising:
• a rod insertable into a grain bed in the grain storage bin;
• a plurality of sensors connected to and supported by the rod, the plurality of sensors comprising:
• a temperature sensor for measuring temperature in the grain bed;
• a fumigant gas sensor for measuring concentration of a fumigant gas in the grain bed;
• and,
• a video camera for detecting presence of pests in the grain bed and for monitoring motion of the pests in the grain bed;
• and,
• a signal transmission assembly connected to and supported by the rod, the signal transmission assembly in electronic communication with the plurality of sensors;
• and,
• a controller electronically connected to the probe, the controller configured to receive data from the plurality of sensors, the controller configured to utilize the temperature in the grain bed, the concentration of the fumigant gas in the grain bed and the motion of the pests in the grain bed to determine if the pests are moving in the grain bed, to determine whether the concentration of the fumigant gas in the grain bed was insufficient to exterminate the pests and to determine a second concentration of the fumigant gas to be applied to the grain bed to exterminate the pests if the pests continue to move in the grain bed.
