Simulasi Autoclave Arduino

Simulasi Autoclave Arduino

          Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat melakukan sterilisasi benda berbasis panas, jadi seperti halnya autoclave yang dapat melakukan sterilisasi, alat ini merupakan simulasi dari autioclave yang terdapat beberapa modifikasi yaitu terdapat timer dan juga terdapat saluran untuk pembuangan udara panas. untuk lebih jelasnya berikut adalah skema dan kodingnya 

a. Arduino

b. Sensor thermocouple tipe K

c. Solid state relay

d. Program Arduino IDE
