2.2 Description of components
The whole system with 3 main circuit boards helps control electrical devices
and connects to the central computer to display and send control commands. The
whole system will use Lora for wireless communication.
IT board
IT box includes 3 main sensors: temperature sensor, Oxygen sensor and PH
sensor used to measure parameters of water environment. Besides, it has an
integrated Camera to directly monitor all activities in the water environment.
Control board
Control Box includes 4 air pump motor along with Compass module and GPS
module to accurately determine the position and direction of the boat. Since then, it
is easy and accurate to control the movement.
Bio tank board
Bio tank box uses 2 cooler and 1 heater to adjust the heat inside the material
tank is always within its allowable range and a Mixer to mix the material tank. In
order to effectively use 2 cooler units, it is necessary to use 2 more water pump
motor to dissipate it.
Node-Red web interface
The Node-Red web interface is a web interface based on the Node-Red
software. It is designed according to the requirements of this project to display data
and image parameters obtained from camera, GPS module and Compass module. In
addition, we can use it to control automatically or manually electrical devices.
Personal Computer
Personal computers are devices that help communicate between humans and
machines. In this project the personal computer is used to display the collected data
and send control commands from people to devices.
Arduino UNO, Mega và Due
Arduino board was designed in the Ivrea Interaction Design Institute intended
for students without a background in electronics and programming concept. This
board started altering to adapt to new requirements and challenges, separating its
present from simple 8-bit boards to products for IoT (Internet of Things)

applications, 3D printing, wearable, and embedded surroundings. All boards are
entirely open-source, allowing users to build them separately and finally adapt them
to their exact needs. We use the Arduino programming language (based on Wiring),
and the Arduino Software (IDE).
We use Arduino instead of another because it is inexpensive, Cross-platform,
Simple, clear programming environment, …

SMART BIO AQUA MONITORING SYSTEM – BIO TANK PART

LoRa is a 'Long Range' low power wireless standard intended for providing a
cellular style low data rate communications network.
Aimed at the M2M and IoT market, LoRa is ideal for providing intermittent
low data rate connectivity over significant distances. The radio interface has been
designed to enable extremely low signal levels to be received, and as a result even
low power transmissions can be received at significant ranges.
The Lora SX1278 module 433MHz uses the SX1278 chip to communicate
with Lora standard, with two important factors being energy saving and super-long
distance. In addition, it has the ability to configure to create networks so it is
currently developed and used a lot in research on IoT. The Lora SX1278 module is
capable of transmitting at a distance of 3000m.
