  Monitoring the coastal area of the Venice Lagoon is of significant
importance. While the impact of global warming is felt worldwide, coastal and
littoral regions bear the brunt more prominently. These areas not only face the
threat of rising sea levels but also contend with the escalating occurrence of
seaquakes and floods. Additionally, the intricate ecosystems of rivers, seas,
and lakes undergo profound transformations due to climate change and
pollutants.
  Employing devices like the SENSWICH floating wireless sensor presented in
this article and similar measurement instruments proves invaluable to automate
environmental monitoring, hence eliminating the need for manual sampling
campaigns. The utilization of wireless measurement devices offers
cost-effectiveness, real-time analysis, and a reduction in human resource
requirements. Storing data in cloud services further enhances the ability to
monitor parameter changes over extended time intervals.
  In this article, we present an enhanced sensing device aimed at automating
water quality assessment, while considering power consumption and reducing
circuit complexity. Specifically, we will introduce the new schematic and
circuit of SENSWICH which had changes in circuit and electronic aspects.
Furthermore, we outline the methodology for aggregating data in a cloud service
environment, such as Amazon Web Service (AWS), and using Grafana for
visualization.
