7. A light-emitting diode (LED) is a two lead semiconductor
light source. It is p-n junction diode, which emits light
when activated.

9. 6. SIM800L GPRS

10. 7. PCB
A printed circuit board (PCB) mechanically
supports and electrically conects electronic
components using conductive track, pads and
other features etched from copper sheets
laminated onto a non-conductive subsrate.
8. Male-Female Cable
In electrical and mechanical trades and
manufacturing, each half of a pair of mating
connectors or fasteners is conventionally assigned
the designation male or female. The “Female”
connector is generally a receptacle that receives
and holds the “male” connector

11. An electrical light is a device that produces
visible light bye the flow of electrical current.

20. Data analysis
(when the less light the lights on)

21. Data analysis
(When the lights go out enough light)

22. DESIGN

23. Conclusion
• The use or application of arduino very much, one of them in the
establishment of this intrumentasi project. As for some of the
points that we can take.
•
1. LDR is an electronic component that can read light. This
component is needed in this project, to know less or
insufficient lighting on the plant.
2. SIM 800L is a modification to this project. Which of these
components that will send commands and information or as a
medium for information concerning lacking or insufficient
lighting. In the component too, we may order the lights to be
turned on.
3. In the overall series, if the lighting is less then the lights will be
turned on, and if the lighting is sufficient then the lights will be
turned off.
