Monitor Suhu Tubuh, Tegangan dan Arus AC, Kemiringan TILT, Flow dan Pressure Udara via Arduino Blynk 2.0

Monitor Suhu Tubuh, Tegangan dan Arus AC, Kemiringan TILT, Flow dan Pressure Udara via Arduino Blynk 2.0 

          Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitor tekanan dan flow udara, arus dan tegangan ac, suhu dan kemiringan. alat ini dimonitor menggunakan Blynk 2.0. sensor yang dipakai diantaranya yaitu MPU6050, PZEM-004t, Ds18b20. untuk lebih jelasnya berikut adalah komponen dan programnya.
