Monitor Suhu Tubuh + BPM + TENSIMETER via Bluetooth Android Sensor MAX30102 dan MLX90614

Monitor Suhu Tubuh + BPM + TENSIMETER via Bluetooth Android Sensor MAX30102 dan MLX90614

 

      

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitor suhu tubuh, bpm dan tensi via bluetooth android. alat ini memang sangat cocok untuk digunakan sebagai alat pengecekan karena mudah dibawa dan juga terdapat fitur bluetooth sehingga bisa dimonitor melalui HP Android. untuk lebih jelasnya berikut adalah daftar komponen dan programnya.  

a. Arduino Uno

b. MAX30102

c. MLX90614

d. Driver Pompa dan Solenoid

e. Bluetooth HC-05

f. LCD I2C

g. MPX5050GP

h. Koding Android
