Membuat Alat HeartRate / HeartBeat (BPM) , Respiration Rate, dan Suhu Tubuh

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat alat untuk monitoring HeartBeat / HeartRate, Respiration Rate dan suhu tubuh, alat ini menggunakan sensor finger clip dan amplifier pendukung untuk heartbeat yang mana outputnya berupa sinyal kotak, untuk respiration rate menggunakan sensor suara dan micondenser yang outputnya berupa tegangan, terakhir yaitu suhu tubuh menggunakan sensor LM35 yang sudah umum digunakan. BPM dan RR digunakan sampling 100 ms selama satu menit. untuk lebih jelasnya berikut program dan skemanya.

a. Minimum System

b. Finger clip

c. Sensor Suara

d. Sensor Suhu LM35

e. Program Bascom AVR

f. Cara Penggunaan Alat

Pertama hubungkan alat dengan power supply, kemudian pasangkan finger clip ke jari telunjuk dan respiration rate ke hidung, lalu sensor suhu tubuh diletakkan di antara ketiak. setelah semua terpasang, tekan tombol start untuk memulai pengukuran, jika telah selesai pengukuran maka akan ada tampilan hasilnya seperti hasil BPM, RR dan suhunya pada LCD.

Membuat JAM DIGITAL dilengkapi SET ALARM dan STOPWATCH menggunakan ARDUINO

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang memiliki fitur jam digital, setting alarm dan stopwatch, sistem kerjanya yaitu alat ini menggunakan Arduino sebagai kendali atau kontroller yang akan mengakses RTC, buzzer dan tombol. terdapat 5 buah tombol yang akan digunakan sebagai selektor menu dan kendali tampilan, buzzer sebagai output alarmnya dan RTC sebagai pemberi data jam dan tanggal. Untuk tampilan display menggunakan LCD 16x2 dengan backlight warna kuning. untuk lebih jelasnya berikut program dan skema alatnya.

a. Arduino UNO

b. LCD Display 16x2

c. RTC DS1307

*KET :

SCL = PIN A5

SDA = PIN A4

d. PUSH BUTTON

e. BUZZER
