Pengolahan Data Sensor Arduino dengan Buzzer dan Relay pada Vertikal Hidroponik

Abstract

In this Journal will be explained about the processing of data from each sensor used by the author to be processed using buzzers and relays. the author uses a waterflow sensor, a pH sensor, a temperature and humidity sensor. from the sensor the received data will be processed by buzzer and relay. relay is useful for turning on and off the lights according to temperature. while the buzzer is used to give a warning to a sensor that is not working properly it could also be that the sensor is damaged. after that the results of the data will be displayed in graphical form on ThingSpeak.
