PLANT1. Plant will automatically be poured with liquid manure in accordance with the soil humidity level .2. Set up the humidity level of the soil based on the ideal humdity level of a plant. As for example, pepper plant will grow nicely, when its humidity level is 50% .3. When the plant humidity is enough,which means the humidity level has reached 50% (example for pepper plant), then the red light will be turned on, and the DC pump will be turned off.4. If the soil humidity level less than its requirement, then automatically the red light will be switched off, meanwhile the green light and the DC Pump switch on. After the humidity level is achieved , the DC pump will be turned off as well as the green light.

COMPONENT

• 1. PROJECT BOARD

2.Arduino UNO

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.

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.

6.CAPASITOR

7. DC PUMP

8.DIODA

A diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other

ARDUNIO’S PROGRAM

How The Program’s

Work ?

In the program it written if we have the threshold value and the threshold value is 800 (based on which plant we choose). 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.

Design of the project

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 3/8 inch pipe
