Performance Optimatization of Yagi Antenna Devices for Detecting Quality Levels River Water Based on Internet of Thing

Abstract

The application of performance optimization of the MIMO antenna system device is basically the use of spatial dimensions in increasing diversity in both reception and transmission. Spatial signal processing then becomes the main concept in the Antenna system. Antenna arrangement is an important part in spatial signal processing, to develop smart city. The design of the antenna array will have an influence on the performance of the Antenna system. A number of MIMO research on the antenna aspect is an interesting research that is currently developing. While the Internet of things is being widely used in today's technological developments. IoT can be interpreted as communication between one device and another using the internet. Advances in IoT technology can facilitate various kinds of work, one of which is to find out water pollution. The components needed in IoT include devices that have an IoT module, devices that connect to the Internet such as Wifi and routers, and a database where everything is collected. The scenario of this system, it is carried out to determine the level of the success of the water turbidity system and the Esp32cam as a microcontroller circuit that uses the Adafruit application and the water turbidity monitor application as internet of things (IoT) technology. Has it worked in accordance with the design of temperature control in surrounding conditions and a dc fan as a smoke exhaust in the room and NodeMcu ESP8266 as a microcontroller the circuit that uses telegram as an Internet of Things (IoT) technology does it work according to the design. The parameters used are the turbine sensor, the esp32cam module, led, the adafruit application and the water turbidity monitoring application for monitoring the state of the water. The turbine sensor serves as an input to detect the turbidity of the water to be tested which will be processed by nodemcu and the output in the form of a display display serves to provide information in the form of text, if smoke is detected, the Nodemcu Esp32cam will send a notification to the telegram application as a medium of information.
