SISTEM PENYIRAMAN TANAMAN MENGGUNAKAN SENSOR KELEMBABAN TANAH DAN ENERGI LISTRIK SOLAR CELL

Abstract

Green Leaf Farmers Group, Tawiri Village, Teluk Ambon District, Ambon City, Maluku Province conventionally uses Alcon machines and dipping machines that require more human power and electricity. An automatic system using soil moisture sensors and solar power sources was created to help farmer groups in automatically watering vegetable plants to increase agricultural yields, introducing solar power as a new renewable energy source. Location survey, tool making, laboratory experiments, to installing tools on site within eight months. The working system of the automatic watering tool; solar panels channel sunlight to the ACC forwarded to the battery and Arduino nano which is equipped with a soil moisture sensor will detect soil moisture so that the water pump machine can be turned off and on automatically at the humidity level detected by the humidity sensor. The 12 Volt DC pump machine, sucks water using a ¾ "PVC pipe and is distributed through a ½" PVC pipe and a butterfly-type sprinkler tap is installed as many as 6.25 steps with a distance of 1 tap to another tap of 2.7 meters. The soil remains moist to ensure soil fertility.
