Abstract

Sensor induktif koil datar mengevaluasi perubahan induktansi bersama dari objek ukur pada kumparan. Koil geometri lingkaran bekerja dengan mendeteksi tanpa kontak fisik dengan objek tersebut yang dibuat pada FR4 Printed Circuit Board (PCB). Osilator LC digunakan untuk mengevaluasi perubahan induktansi dari dua sensor identik dalam struktur diferensial dengan massa penganggu, yaitu tembaga berilium (Cube) bergerak maju mundur antara sensor. Batas pengukuran dengan jarak minimum diperoleh frekuensi sebesar 3,45MHz untuk sensor koil datar 1 dan 2,41MHz untuk sensor koil datar 2. Linierisasi menunjukkan sensitifitas suatu sensor dengan nilai dua kali dari sensitifitas satu sensor.

Abstract

The development of plants on a plantation is highly dependent on providing sufficient water for the plants.Hence, it is needed to have a optimal smart watering for plantation that is able to distribute water for plants efficiently. In this work, we developed an off-grid solar power plant to support a smart watering system. This solar power plant uses polycrystalline panels that function to absorb solar energy. Second, there is the SCC (Solar Charge Controller) which is used to charge the battery and regulate power from the battery to the load to keep the battery from overcharging. Then there is a 500 watt psw inverter. The battery is also used as a storage of the power that has been generated. The power that has been stored in this battery still be used to turn on the pump to water the plants, and it is also useful to turn on the existing sensors which will be input to the microcontroller then give the command to turn on the pump. Based on the collected data, it is known that the system requires an average power of 783.56 W for one hour
