This arrangement aims to measure seawater quality parameters, their wireless transmission as well as their posting on the internet. The quantities measured are temperature, pH and turbidity, while there is also the possibility of using additional sensors. The construction?s function is based on the arduino microcontroller and consists of two main parts. The first part includes a circuit of sensors which is watertightly closed in a container that can remain for a long time under the surface of the sea. In addition, a GPS module has been placed in the construction to determine the position of the container on a map. The indications of the above sensors are transmitted wirelessly to the second circuit that is outside the water and through which the information is collected, recorded in graphs and posted on a website. The value of this construction lies in the fact that the monitoring of the parameters that...
