    rims-arduino-library

    Recirculation infusion mash system library for Arduino

    This library implement RIMS controls for home brewers. For definition of a RIMS, see https://tinyurl.com/j3lyuyc For me, an Arduino micro controller + a LCD Keypad shield was cheaper and a lot more customizable than a commercial PID controller. So, with this library, a commercial PID controller is unnecessary. Automatic PID tuning toolkit is also included. Temperature can be read with a thermistor, a resistance temperature detector (RTD) or any custom temperature probe. Heater is controlled with pulse-width modulation (PWM) of a solid-state relay (SSR). Documentation : https://tinyurl.com/y7579v6a
