Abstract Automation is a technology used to carry out work processes or procedures without human assistance. Greenhouse automation is carried out related to the many operational activities in the greenhouse that involve many human repetitive activities. Some of them are related to fertilizing, watering, spraying pesticides and others. In the current era of the industrial revolution 4.0, manual activities that use human labor began to diminish and were replaced with automated systems and devices in order to streamline the operation of a work field,. PLCs can be defined as a micro-computer based controllers that use instructions stored in memory that can be programmed to implement logic, sequencing, timing, counting and arithmetic functions through digital or analog input / output (I / O) modules, to control machines and processes. This PLC is commonly used in the industrial world as an automation tool for production machines. PLC can be implemented as an automation tool in a greenhouse in this case as an automatic watering system for plants. This research resulted in a prototype of an automatic watering system on a clock based and combined clock-sensor based greenhouse that can run simultaneously on the same PLC.
