    Abstract
    Telah dirancang suatu alat sebagai alat ukur sebuah pengukuran PH tanah dan RH tanah dengan menggunakan mikrokontroler ATMega 8. Alat ini terdiri dari dari Resistor,SIM 800L, Konverter AC-DC. Alat ini digunakan untuk untuk mengukur derajat keasaman dan kelembapann tanah dengan melaui telepon genggam (SMS) Prinsip kerja sistem ini secara umum adalaha dimulai saat catudaya sistem diaktifkan. Kontroler akan melakukan tugasnya setelah reset awal dan inisialisasi. Kontroler akan membaca data sensor, dimana sensor akan memulai membaca data dalam bentuk raw data . Setelah memperoleh data hasil olahan, data hasil tersebut kemudian ditampilkan pada telepon genggam.yang dikirim menggukan mode GSM SIM800L. Hasil perbandingan ketiga algoritma Hierarchical Clustering tersebut menunjukkan bahwa jarak antar cluster terpendek, yaitu 5,10593 diperoleh menggunakan metode Single Linkage.
     
    An instrument has been builded as a measuring devce to measure the level of pH and Rh with Atmega8 as the base. This instrument consist of resistor, SIM 800L, converter AC/DC. This instrument is use for measuring soil the degree of Acid and humidity via seluler phone(SMS). In general, the working procedure of this instrument start at the activation of power source. Controller Will do its task after the first reset and initialitation. Controller then read the sensor data, which come from the raw data read by that sensor .After its get a processed data, that data will be send to the sellular phone in the form of SMS with GSM SIM800L. The compared result between the three hieralchical cluster algorithm data show that the distance between the shortest cluster, which 5,10593, was got using single linkage method.
