The proposed system addresses this by using an intelligent earth monitor connected to a GSM modem to transmit earth line state data via short messages. When installed, it can detect if the earth line is connected or disconnected and display this information at a remote monitoring center. The system has hardware components like a microcontroller, sensors, and GSM modem and requires software like Embedded C and a VB program for monitoring.
The document describes a design for an embedded web-based remote monitoring system for laboratory environments. The system uses an ARM microprocessor as the main controller connected to sensor networks, cameras, and communication modules. An embedded Linux system and web server allow remote monitoring and management of environmental data and video images through a web browser. Managers can view data, control equipment, and receive alerts. The system was implemented and experimental results showed it effectively enabled remote monitoring and local management of laboratory environments.
A remote online monitoring system for damsudhakar5472
This document proposes a remote online monitoring system for dams that uses sensors to monitor parameters like temperature, displacement, load, and stress in real-time. The sensor data is sent via GPRS to a computer server where it is stored and analyzed. This allows dam conditions to be monitored centrally without needing manual on-site measurements. The proposed system interfaces sensors with a PIC microcontroller that sends abnormal sensor readings via GPRS. Authorized users can then access the sensor data remotely for monitoring dam safety.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Ship detection with wireless sensor networks
1. Ship Detection with Wireless Sensor Networks
Abstract
Intrusion detection on the sea is a critical surveillance problem for harbor protection,
border security, and the protection of commercial facilities, such as oil platforms and fisheries. In
this paper, we present an innovative solution for ship intrusion detection. Equipped with threeaxis accelerometer sensors, we deploy an experimental Wireless Sensor Network (WSN) on the
sea’s surface to detect ships. Using signal processing techniques and cooperative signal
processing, we can detect any passing ships by distinguishing the ship-generated waves from the
ocean waves.
Existing System:
The traditional methods of detecting ships entail the use of radars or satellites which are
very expensive. Besides the high cost, satellite images are easily affected by cloud cover, and it
is difficult to detect small boats or ships on the sea with marine radar due to the noise or clutter
generated by the uneven sea surface. Hence we go for new system.
Proposed System:
In this system, the ship intrusion is going to be detected by placing three axis
accelerometers at the sea surface. The waves which are generated by the ocean and intruder ships
are analyzed by the accelerometer and the signal is processed by the controller. The controller
will transmits the data from the sea-shore section to the monitoring in wireless communication
mode called Zigbee. It’s a communication medium which operates in the frequency range of
2.4GHZ. The accelerometer will distinguish both the signals and sends an individual data to the
controller. The accelerometer and ship status is displayed in LCD.
