The document outlines the development of a smart lamp utilizing a GSM module (SIM800L) as part of a greenhouse project, highlighting its main components such as an Arduino processor, sensors, relays, and other electronic elements. It describes the functionality of the system, including how it can monitor light intensity and control the lighting based on input from a light-dependent resistor (LDR). Additionally, the document includes the programming code used for the Arduino, which enables communication and control of the lamp through SMS commands.

- 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.
