Resumen:	Water pollution endangers the surrounding environment of freshwater reservoirs. In fact, in Mexico there have already been cases of massive fish deaths, affecting the surrounding environments and people whose economic activity depends on the body of water. In 2020, 63.67\% of Mexico's water bodies were considered contaminated. To prevent and avoid these situations, a prototype of Water Quality Monitoring System (WQMS) based on an Unmanned Surface Vehicle (USV) was proposed. The WQMS was based on a catamaran-type boat and designed to monitor freshwater bodies, similar to lakes and dams. The WQMS monitors three parameters of vital importance for the development and survival of aquatic life (pH, dissolved oxygen and temperature). This system was used to compare the behavior of the sensors when the USV is at rest or in motion, and to observe the energy consumption, in order to verify if continuous monitoring allows reducing the monitoring time while the measurements maintain a similar precision in point-to-point monitoring. As a result, it was observed that in continuous monitoring measurements are affected by the movement of the USV, however, it is observed that the measurements for the pH sensor remain within the same range of values (the value in rest to the same minus $0.2[ pH]$), while in the case of dissolved oxygen the values increase for a while (due to the response time of the sensor) until reaching an almost constant value. In the case of the temperature sensor, it was also affected, however, this effect is very small. By comparing the measurements and energy consumption with an ideal case, it is verified that continuous monitoring maintains similar measurements and shorter monitoring time than point-to-point monitoring.
