IOT – ENABLED SEA WEATHER AND POLLUTION MONITORING STATION

Abstract

Unlike weather on land, sea weather is highly unpredictable and changes drastically at times. Keeping track of sea
weather always is a very tough task. Also, sea pollution is a growing issue of concern and the first step to
controlling pollution is measuring it. Another problem is the unavailability of cellular or other data networks in
sea or data transmission. It is necessary to always use small sea weather stations with own data transmission
capability in the sea to get data about these details. So, we hereby design and develop a small sea weather as well
as sea pollution monitoring station that can transmit this data over to the monitoring station on sea shores. The
system uses a range of sensors all controlled controlled by an Arduino UNO in order to achieve this task. Along
with it we also develop a receiver system to receive and display the data from the transmitter. The transmitter unit
is always in the sea and its not possible to constantly charge itself from time to time, so we use a solar panel to
allow it to generate its own power and keep working in the sea. The transmitter uses turbidity sensor to check
pollution, DHT 11 for Temperature and Humidity levels above the Sea water. Also, the system has an
accelerometer sensor to detect sea state, depending on weather the sea is rough or calm, the accelerometer
throws values that can be used to check if sea is calm or rough. These values are constantly monitored by the
Arduino UNO and transmitted at certain intervals by through a n RF transmitter. The transmitter is fitted with a
high gain antenna in order to achieve maximum transmission range. Now the receiver unit is developed using a
Node MCU and display in order to receive data transmitted by the transmitter buoy and display it. The receiver
unit consists of a n RF receiver with an antenna that is used to receive the data values transmitted by sea unit. This
data is now received and processed by the Node MCU. The Node MCU now displays these values on the lcd
display. If a value is not normal or beyond set range it also sounds a buzzer alert and displays alert in order to
notify station officers to act and warn ships/people in the vicinity.
