ABSTRACT

Water has an important role for plants for the photosynthesis process where moisture is water that fills the pores in the soil. Where is the soil moisture sensor which reads the moisture in the soil which has been controlled by the arduino nano. The advantage of this watering tool is that it is done automatically and a soil PH sensor that reads acidity or alkalinity in the soil where this tool uses the internet of things which can see the value of humidity and acidity sent from nodemcu via the internet and can see it from the telegram application. In making this tool, data collection has been carried out such as field studies, system design, implementation, testing and evaluation, literature study and making flowchart for the workings of this tool. To use this tool requires a current voltage of 5,22 V. This tool will work if the soil value on the soil is more than 700 dry soil then the pump will be ON if the value is less than 400-700 moist, less than 400-200 wet then the pump will be OFF where this watering tool will work if the soil on the plant is dry and will activate the pump to provide water and this tool must be placed in a safe place to avoid children and rain.
Key words : Watering plants, Internet of things, soil moisture and soil PH
