Bluetooth Beer Brewing – Hackster Weblog
Brewing your individual beer has develop into a pastime for a lot of, however what in case you’re bored with manually controlling each step of the method? For some nice concepts on tips on how to get that carried out, make sure you take a look at LeapingLamb’s “Brew in a Bag” Bluetooth controller.
An Arduino Uno housed in a recycled enclosure acts as the center of the setup, taking temperature readings from the batch-in-process by a number of waterproof DS18B20 temperature sensors. A solid-state relay quickly switches the heating ingredient beneath PWM management to maintain issues on the desired temperature, and pair of mechanical relays suffice to change the rig’s fan and pump on and off at a slower velocity.
Consumer interface is by way of an HC-05 Bluetooth module, permitting LeapingLamb to handle every part remotely from a customized Common Home windows Platform App.
Whereas a reasonably easy construct at this level, LeapingLamb notes that since there are a number of I/O pins left on the Arduino controller, the mission may very well be expanded considerably with extra inputs or management elements as wanted. Additionally, past merely wiring issues up, the brew vessel underwent vital modification to accommodate these new elements, including a big quantity of effort to the growth course of.
