Pembuatan Sistem Penyiraman Otomatis Berdasarkan Kelembapan Tanah untuk Menghidupkan Solenoid Valve dengan Komunikasi Wireless

Abstract

Technological advances from time to time have developed rapidly so that it can provide many conveniences for humans to carry out daily work such as taking care of plants in the garden. Plants that are not cared for and lack of water can experience slowed growth. Therefore, caring for plants requires water for watering. Regular watering is an important routine to keep plants growing and thriving. Watering that is done regularly before the soil is dry can be done by utilizing soil moisture sensor technology that is connected wirelessly using the nRF24L01 wireless module to the water faucet to control watering. This technology can be used to build a system that functions to water plants in the garden. Communicating sensors with water taps wirelessly by utilizing 2.4 GHz RF waves is a control system that does not require internet, so the absence of an internet network is not a problem. The results achieved after this research was carried out were that an automatic watering system was produced by utilizing 2.4 GHz RF waves between the sensor and the water tap to water plants.
