Aplikasi Mikrokontroler pada Sistem Penyiram Tanaman Otomatis dengan Menggunakan Sensor Cahaya Dilengkapi dengan Buzzer dan Tampilan LCD

This study aims to develop a system of crop spraying in the greenhouse using a microcontroller ATMega8535 automated. The benefits of automa-tion is the reduction in consumption of spraying time on the process of spraying, reduced manpower requirements, and increase the volume of spray so that the plants are watered harvest results as expected. The research was done by design, give depth and implement components system that includes: (1) mikorokontroler as process controllers, (2) DC motor as a driving force to open and close the roof, (3) the LDR as the light detector, (4) the detector TGS 2610 air humidity, and (5) water sensors to detect rain.
