Post harvest stored grain losses remain a problem. Vigilant post-harvest grain management is the most cost-effective means of increasing the world's food supply. Spoilage of bulk-stored grain leads to decreased nutritional value and poses health hazards due to the formation of irritating volatile metabolites inside grain bins. Quality changes in the stored grain bulk can be identified by various odors as well as increase in carbon dioxide. This paper provides information and analysis about the potential of sensors for grain quality monitoring, a brief overview of the innovative research on the development of sensors and future perspectives. "On the go" grain quality monitoring gas sensors, electrostatic sensors for particle size measurement for grain dust, moisture, and acoustic sensors are identified as potential instruments to be employed inside the grain bin for monitoring the quality of grain and for increasing the shelf life of stored grain.(Download PDF) (Export to EndNotes)
