Temperature regulator for mash tun

INTRODUCTION

    I am student of Silesian Univesity of Technology. I major in Electronics.

I would like to start my adventure with brewing.

TECHNICAL DETAILS

    Project is about PID temperature regulator. Output of the regulator is PWM signal witch controls SSR relay. Parameters are set by 4 buttons and 16x2 display. Eveything is controled by Arduino Nano.

    The temperature measurement is carried out on DS18B20. Its digital temperature sensor. Its comunicating by One-Wire interface.

    As heating element I used Two special brewing heaters 1750W made with acid-proof and stainless steel. The heaters will be controlled by SSR relay. 

Words to PCBWay

    As student i have limited budget. It would be really nice, if I recived your support.
