Abstract
Tanda-tanda vital kesehatan manusia dapat diketahui dari suhu tubuh, pernapasan, tekanan darah, dan denyut nadi. Dalam tugas akhir ini, dirancang sebuah prototipe monitoring suhu tubuh manusia berbasis android menggunakan koneksi bluetooth dengan performansi dalam bentuk jaket yang terdiri dari tiga buah titik pengukuran. Langkah-langkah yang dilakukan untuk merancang sistem pengukuran suhu tubuh adalah dengan mendesain sistem perangkat keras dan perangkat lunak. Sensor yang digunakan adalah IC-LM35 yang tersebar di tiga titik pengukuran. Sensor ini sebagai pendeteksi perubahan suhu tubuh, kemudian hasil perubahan suhu akan dibaca dan diproses pada mikrokontroler ATMega8a-pu. Setelah data terproses, selanjutnya data akan dikirimkan ke perangkat android melalui koneksi bluetooth. Setelah dilakukan pengukuran dan analisis data, dapat diketahui bahwa alat ini memiliki respon dinamis settling time sebesar 5 menit. Jarak maksimum koneksi perangkat adalah 35 meter, dan kemampuan baterai sebesar 9 volt selama 90 menit. Alat ini memiliki nilai eror akurasi sebesar 0.29150C, eror presisi sebesar 0.8°C untuk sensor A (mulut), dan nilai eror akurasi sebesar 0.4149°C, eror presisi sebesar 0.2974°C untuk sensor B (ketiak kanan), dan nilai eror akurasi sebesar 0.3846°C, eror presisi sebesar 0.5956°C untuk sensor C (ketiak kiri)
