Estimation of durability of rice grains using sensors and mobile technology

The measurement of moisture content in Rice granules is important for storage of rice. The moisture content present in the rice granules affects the quality and toughness of the final product. Existing systems that were proposed to measure the moisture content of rice granules are not practical enough. Their performance is influenced by material density and packing. The official oven method consumes more time. The moisture content of rice granules is measured by the equilibrium relative humidity technique [ERH]. The equilibrium relative humidity, and temperature, of rice granules were measured by using temperature and relative humidity sensors. Sensors are calibrated to improve accuracy. The moisture content was calculated by using an equilibrium moisture content model. The data collected from the sensors are sent to the user which gives intimation about the prevailing conditions in the storage place as a message. According to the message, the prevention methods are listed. The error of the moisture content determined with this method was within 0.5% w.b. at moisture.
