Monitor Kemiringan Menggunakan IP Local Sensor GY-521 (MPU-6050)

Monitor Kemiringan Menggunakan IP Local Sensor GY-521 (MPU-6050) 

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mengukur tingkat kemiringan suatu dataran atau benda dengan menggunakan sensor GY-521 / MPU-6050 dan mikrokontroller yang dipakai yaitu wemos D1 mini. alat ini bisa memonitor tingkat kemiringan dengan menggunakan IP Address local sehingga membutuhkan suatu router sebagai medianya pengiriman sinyalnya dikarenakan menggunakan wifi. untuk lebih jelasnya berikut adalah komponen dan kodingnya.
