Rancang Bangun Alat Pemantauan Cuaca Berbasis Internet Of Things
Weather is very important for humans, because humans are creatures that socialize and often travel, so the weather determines whether human activities are carried out or not. Today there are many tools to find out or monitor weather conditions, even the BMKG on its website also plays a role in providing information from the weather conditions in a place. However, there are several other problems that exist in the current monitoring system, the weather monitoring tools in circulation today are relatively expensive so that people sometimes cannot reach these expensive tools. In terms of BMKG website information, weather monitoring data in some areas is incomplete or not all data is available. The weather monitoring tool is made using NodeMCU 8266 as a microcontroller that is connected to blynk as a data visualization application in the form of graphs. This tool is also designed with DHT 11 sensor, rainfall sensor, wind speed sensor and wind direction sensor. Tool testing is done by comparing the value obtained by the tool made and the value obtained from the Davis Weatherlink Station tool. The results of the hardware design are made by inserting the DHT 11 sensor, rainfall sensor, wind speed sensor and wind direction sensor into a box measuring 10cm x 7.5cm x 3.5cm. The results of testing the tools used for 1 week get accuracy above 82%.
