Abstract

The development of science and technology triggers the agricultural sector to increase efforts that aim to obtain high productivity with the best quality. Knowledge of weather and climate is very important in agriculture so that farmers are able to follow the changes that occur and are able to overcome the problems that will occur due to weather changes. So far, information obtained by farmers on the weather changes that occur is still lacking due to the limited amount of information sent by the government due to the limited facilities and infrastructure and the timeliness of information received by farmers is not on time. In the design, the climate / weather elements measured by this device is air temperature, humidity (DHT11), sunlight intensity (GY-302), soil temperature at a depth of 5cm, 10cm, 15cm (DS18B20), wind speed, direction compass and rainfall intensity (Weather Sensor Assembly p / n 80422), as the main controller used arduino mega2560 microcontroller. The value obtained from the measurement of the weather sensor will be recorded on the flashdisk. This value will also be recorded online on the ThingsPeak website and can be accessed online using the ThingView app or accessing the ThingsPeak website. This tool is also equipped with a 18650 battery with a capacity of 3000mAh as a second power source when electricity from the State Electricity Company (PLN) goes out. Data stored on the Thingspeak website can be downloaded to make it easier for users to observe further weather sensor data, as well as data stored on flashdisk with txt format can be opened with Microsoft Excel to facilitate further data analysis.
