Tensimeter Digital Online Blynk + BPM Heartbeat

 Tensimeter Digital Online Blynk + BPM Heartbeat

         Pada kesempatan kali ini saya aka menjelaskan mengenai bagaimana cara membuat sebuah tensimeter digital yang dapat dimonitor secara online menggunakan aplikasi Blynk. alat ini layaknya seperti tensimeter yang dapat mengukur sistole dan diastole serta juga dapat mengukur bpm. yang harus diperhatikan pada alat ini yaitu harus dilakukan kalibrasi secara berkala agar didapat hasil yang akurat.

a. Wemos D1 mini

b. Sensor MPX5050GP

c. LCD 16x2 + I2C

d. Sensor Bpm Max30100

e. Driver Pompa dan Solenoid

f. Skema Alat

g. Program Arduino IDE
