This monitoring system utilizes Internet of Things technology. This study uses component input outputs, including NodeMCU ESP8266, RTC sensors, relays, LCDs. The software used for system monitoring uses Blynk software. The results of the study obtained success reaching 100% with automatic spraying successfully functioning, when the time was 16.00 WIB the pump would automatically start spraying pesticides and when the time showed 16.01 the pump would stop spraying.
