Various sensors have been developed to detect the state of water. The sensors that measure snow are especially needed in various fields, such as traffic safety and mainte nance, and the management of outdoor institutions. How ever, since these sensors are based on fixed-point observa tion, they need a wide range. In order to perform precise observations many sensors, installed relatively short dis tances apart, are required. However, this can become ex pensive. As a result, we have developed a simple, inexpensive sen sor that can detect snow coverage and melting information at one point and use it to calculate the presumed values at different locations, what we call a ”wide range presumptive method”. Before calculating the wide-range values, the ac curacy of the fixed-point observation was verified. In this experiment, the validity of applying the similarity rule to snowmelt characteristics was also verified. Consequently, we propose to use the similarity rule to determine the envi ronment information, ie. snow coverage and melting, sur rounding the sensor on the basis of calculations from data at the point of the sensor.
