By revealing at least a part of a tube above the water surface, water quality data detected below the water surface is transmitted. The water quality monitoring device sequentially includes, from top to bottom, an upper tube, a first connecting member and a middle tube. The water quality monitoring device appearing slightly long tubular further consists of a signal transceiving module in the upper tube, a monitor in the middle tube, and a sensing portion protruding out of the middle tube. A water quality monitoring system can further be formed by connecting a plurality of water quality monitoring devices to a network to monitor water quality conditions at a remote end, thereby monitoring water quality conditions in real time. ## Claims ### Claim 1 A water quality monitoring device, comprising: an upper tube, having an opening at a lower end thereof; a middle tube, having an opening at each of upper and lower ends thereof; a first connecting member, having an upper end thereof connected to the opening at the lower end of the upper tube, and a lower end thereof connected to the opening at the upper end of the middle tube; a monitor, having a signal transmission wire sequentially passing an interior of the middle tube and the first connecting member, the monitor being in either one of two configurations of: configured at a lower end at the interior of the middle tube and protruding out of the opening at the lower end of the middle tube, or configured at an exterior of the middle tube and connected to one end of the signal transmission wire, the end of the signal transmission wire being fixed at the lower end of the interior of the middle tube; and a signal transceiving module, installed at an interior of the upper tube, coupled to the signal transmission wire. ### Claim 2 (depends on 1) The water quality monitoring device according to claim 1, further comprising a sealing ring between the first connecting member and the middle tube, wherein an accommodating space is defined at the interior of the middle tube by the first connecting member and the monitor configured at the lower end of the middle tube so as to preserve gas in the accommodating space therein. ### Claim 3 (depends on 2) The water quality monitoring device according to claim 2, further comprising: a lower tube, having an opening at an upper end thereof, at least one window connecting to an interior thereof on a tube wall thereof, and a dilated opening matching an outer diameter of the middle tube at the upper end thereof; and a second connecting member, having an upper end thereof connected to a lower end of the lower tube. ### Claim 4 (depends on 3) The water quality monitoring device according to claim 3, further comprising: a counterweight block, being in at least one of six configurations of: in the middle tube, outside the middle tube, in the lower tube, outside the lower tube, in the second connecting member and outside the second connecting member. ### Claim 5 (depends on 4) The water quality monitoring device according to claim 4, wherein a position at which the counterweight block is configured causes a center of gravity of the water quality monitoring system to locate below a middle of the water quality monitoring device, and simultaneously causes an antenna portion of the signal transceiving module to be revealed above a water surface when the water quality monitoring device is deployed in water. ### Claim 6 (depends on 3) The water quality monitoring device according to claim 3, wherein the lower tube comprises a corresponding net mask covering the at least one window. ### Claim 7 (depends on 1) The water quality monitoring device according to claim 1, wherein the monitor comprises at least one sensing unit, and the at least one sensing unit is at least one selected from a temperature sensing unit, an electrical conductivity sensing unit, an oxidation-reduction potential sensing unit, a dissolved oxygen sensing unit, a pH value sensing unit and an ion-selective electrode sensing unit. ### Claim 8 (depends on 1) The water quality monitoring device according to claim 1, further comprising a solar power module provided at an upper side or around a tube of the upper tube, and the solar power module is coupled to the signal transmission wire. ### Claim 9 (depends on 3) The water quality monitoring device according to claim 3, further comprising an end tube having a pointed portion at a lower end thereof, an upper end of the end tube connected to a lower end of the second connecting member. ### Claim 10 (depends on 3) The water quality monitoring device according to claim 3, wherein the second connecting member is connected with an anchor member. ### Claim 11 (depends on 1) A water quality monitoring system, connected to a remote server to provide water quality data to a terminal device, the water quality monitoring system comprising: a plurality of water quality monitoring devices of claim 1; and a wireless router, wirelessly connected to the water quality monitoring devices so as to obtain water quality data detected by the monitors of the water quality monitoring devices. ### Claim 12 (depends on 11) The water quality monitoring system according to claim 11, wherein the signal transceiving modules of the water quality monitoring devices are radio-frequency (RF) transceiving modules to thereby establish RF communication with the wireless router. ### Claim 13 (depends on 1) A water quality monitoring system, connected to a remote server to provide water quality data to a terminal device, the water quality monitoring system comprising: a plurality of water quality monitoring devices of claim 1, wherein the signal transceiving modules of the water quality monitoring devices are signal transceiving modules compliant to mobile communication technology standards.
