In conclusion, a smart watering
plant system or usually called automatic irrigation system will build our life
easier and advantageous. Smart watering plant system are the fortune
development for home garden. This can be as a result of the program that has
been setup is a lot of appropriate for small home garden. Nowadays, Internet in
Malaysia becomes the most platform for complimentary discussion and
communication between them. 81.8% of every social unit in Malaysia buy the
fastened broadband. Since this project are using internet, individuals will
take advantages of it and applied to the project.
Internet
of Things (IoT) is main feature in this project. This project have 2 type of
function which is automatic
and manual. When the system running, a soil moisture sensor and DHT22
(temperature and humidity sensor)will collect data and transfer
mainboard NodeMCU ESP8266 and will display monitoring data on Blynk apps at
smartphone. A user don’t worries anymoreto plant their plant to make sure
plant get enough content water and idea temperature also surrounding air.
For
automatic, when the sensor detect soil content is dry and upper than moisture
threshold was set the relay will triggered and automatic turn ON the motor
pump. After soil moisture enough for plant the motor pump will automatic turn
OFF. During the automatic system running, notification email will be send to
user and the user can monitoring data on Blynk apps at smartphone.
For
manual, only used for certain time for example if the user plant the type
species what need more water ,low temperature and high humidity like tomato and
strawberry. So for this case only the user will run with manually. By pressing
the push button manual on Blynk apps, relay module directly triggered and will
turn ON the motor pump. A user can control manual from long distance but have a
limit range of connection.
Auto
backup power supply also with one main system in this project. Basically the
normal system using a grid supply 240 volts to running the system. So when
black out happen a relay will automatic triggered and switch to solar energy
supply. At morning until afternoon around 10am-3pm the process charging happen
when the solar panel will absorb a heat of sunlight and generate an electrical energy.
An electrical energy was generate from solar panel will be store at battery.
The charger controller has been connect between solar panel and battery. Main
function of charger controller is to stabilize the current. If current not
stable it will cause/blow the load. Another function is to cut off the current
when battery is full. If battery was full it not charging anymore because over
load current will be transfer to ground.
Automatic
plant watering system provided a low cost feature and portable that will
attract many people to look and take advantages to install at their home. This
project will provided a user can be saving more water and reduce wastages of
water from over irrigation plant. A user no need more to watering their plant.
It is also provide saving of bill electricity by install solar energy system
and can be backup power supply when blackout happen. Finally, this project has
successfully function and has been achieved the main objective on this project.
