4. PURPOSE
1. Understand the using of Arduino Uno Mikrocontroler
2. Understand the funtion of Yl-69 Sensor
3. Understand the step of fertilizational control base on humidity
parameter
4. Build the simple automatic fertizition system by simple technology
based
6. 1. Set up the humidity level of the soil based on the
ideal humdity level of a plant, Ex : 78,20%
2. When the plant humidity is enough,then the red
light will be turned on, and the AC pump will be
turned off
3. If the soil humidity level less than its requirement,
then automatically the red light will be switched off.
4. The green light and the AC Pump switch on
5. After the humidity level is achieved , the AC pump
will be turned off as well as the green light

3. SENSOR YL-69
This is a simple water sensor can be used to detect soil moisture
when the soil moisture deficit module outputs a high level, and vice
versa output low. Use this sensor produced an automatic
plant watering device, so that the plants in your garden without
people to manage.
13. COMPONENTS3
5. RESISTOR
A resistor is a specialized electrical component that provides
resistance as a circuit element. Resistors are passive, which means
they are not affected by the current they carry.
18. COMPONENTS3
9. SOLID STATE RELAY
A solid-state relay (SSR) is an
electronic switching device that
switches on or off when a small
external voltage is applied across its
control terminals .

14. OBJECT PLANT CELERY
Type of Plant
Division : Spermatophyta
Sub Division : Angiospermae
Class : Dicotyledonae
Familly : Apiaceae
Genus : Apium
Spesies :Apium Greveolens
24. COMPONENTS3
14. OBJECT PLANT CELERY
Term Growth :
1. The temperature at seedling 9-20 â°C, 15-24 â°C while further
growth.
2. Soil Moisture 78-90% moisture.
3. Irradiation is sufficient sunlight.
4. The optimum rainfall of 60-100 mm / month .
5. Ideal Soil: Fertile, organic matter, air and water good governance.
6. The optimum pH from 5.5 to 6.5.
7. Raising altitude 1000-1200 mdl example in Lembang and Cianjur.
26. COMPONENTS3
15. FERTILIZER
1. Stimulate and promote the growth of leaves.
2. Stimulate new leaf buds and twigs.
3. Accelerate the formation of flowers and fruit.
4. Prevent plants from wilting of leaves, flowers and fruit.
5. Prevents plants from the loss of leaves, flowers and fruit.
6. to make a plant be green leaves and fresh
BENEFITS
28. PROTOTYPE4
That is the design project of automatic fertilization
based on soil humidity utilising Ardunio and YL-69
Sensor. With the 4 inch pipe for growing media and
watering medium using 5/8 inch pipe
29. Start

33. How The Programâs Work ?
In the program it written if we have the threshold value and the threshold
value is 800 (based on which plant we choose) as
800
1023
đĽ 100% = 78,20 %.
Thus, when the value detected by the sensor shows less than the threshold
value , the red LED will shut down or Off. Menawhile, green LED and the
pumps would turn on. That indicates that the plant needs to fertilization. In
reverse, when the value hits more than the mentioned value or equal to that,
red light will turn on meanwhile green light and the pump will shut down.
This indicates that the plant does not need the fertilization.
