Abstract

The development of network communication technology is currently developing rapidly, one of which is the use of LED lights that are not only used as lighting in the room but can also be used as a medium of data communication between users through light media. VLC is the latest innovation in the field of data communication that is currently being developed where the process of sending data used light media.. The simulation  of sending data using VLC can be done on the transmitter and receiver side by using Visual Studio application as an application that can visualize the process of sending data. By using this system the process of sending data every bit from transmiiter to the receiver can be seen so that the success rate of sending data can be easily seen by the user. system used arduino Uno as microprocessor. From the test results obtained the success rate of displaying images sent by the transmitter is 100% with a maximum distance of 50 cm with an image capacity of 20 KB with a delivery time of approximately 30 minutes.

Abstract

Air pollution is a disaster that can indirectly interfere with human health, Indonesia is the third highest country in the world that has pollution levels, one of the types of pollution that threatens public health is the increase of CO, NO2 and SO2 level in the air. With the increasing level of air pollution in the city, it requires a device that can monitor air pollution in a real time. By integrating air sensor and Raspberry Pi as data processor and using LoRa module as transceiver module, then the process of transmitting data from transmitter to receiver can be done directly without connected internet. In a test, the system can transmit intensity data information by wireless system on Line Of Sight (LOS) scemes at a maximum distance of 1.7 Km and Non Line Of Sight (NLOS) scheme at a distance of 400 meters with a average delay is 2 second.
