Monitor Suhu Non Contact MLX90614 LCD TFT Graphic ILI9341 ESP32

           Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat mendeteksi suhu kemudian data suhu tersebut ditampilkan ke lcd TFT ILI9341 dengan grafiknya. jadi alat ini hanya monitor suhu saja secara non contact atau tidak menyentuh, sehingga sangat bagus untuk kebutuhan industri yang ingin memonitor suhu tanpa harus menyentuh objectnya. untuk koding dan skemanya seperti berikut ini.

a. Skema Rangkaian Alat

R1 - R6 = 2k2 ohm

R7 - R12 = 3k3 ohm
