Abstract: An apparatus for measuring the amount of snow cover and snowfall using electrical conduction. The apparatus includes: a collection container in which the snow is flowed and is piled up and which is opened upwards; a supporting mount for supporting the collection container; a first conductor that is disposed on a bottom of the collection container and contacts the snow piled up on the collection container; a plurality of second conductors that are disposed spaced apart from each other on sidewalls of the collection container in a height direction of the collection container and contact the snow piled up on the collection container; a power supply unit that is electrically connected to the first conductor and the plurality of second conductors; and a detection sensor for determining that the first conductor and the second conductors are electrically connected to each other, based on the snow piled up on the collection container.

Abstract: A groundwater profile monitoring system includes a groundwater sensor configured to sense a state of groundwater; a driving unit including a sensor cable to which the groundwater sensor is connected at one end thereof and configured to vertically move the groundwater sensor; a data logger configured to receive and store sensing information sensed by the groundwater sensor and transmit the sensing information to a designated server; and a power supply unit configured to produce electric power using solar energy and supply the produced electric power to the driving unit and the data logger. Since a profile material of vertical groundwater according to a depth of a tube well can be continuously collected by using one sensor, an accurate groundwater related material can be collected more efficiently.
