WeBrewSpindel_V1.0

thingiverse

hey people, i love to brew my own beer and I also a beginner in programming with Arduino and IOT. So i was checking, about the iSpindel or other Hydrometer (130€). On the one hand, it was to complex or on the other hand was to expensive. So i here is my solution for it. And it cost you only a few $ or € (~30€ or less) and easy to set up/check data). You can check with it the tempature, °Plato, pitch and voltage of your battery. Here is what you need: - printed weBrewSpindel (infill 20% 0.15mm) - 18650 LiPo (mine is USB 3.7 V 1400 mAh) - NodeMCU-ESP32 - GY-521 Gyroscope - XXL PETLING with cap - mini switch - some wires - lead weights to get the pitch in clear water Steps: 1. print weBrewSpindel 2. glue and attach the nodeMCU like on the chart 3. do the wireing 4. create your thingspeak account - you will need 4 fields: temperature, °Plato, pitch and voltage 5. setup the code - add your wifi SSID and PW - add your thingspeak API key (for writing) - make some mesurements with kalibration excel sheet and replace the formula (more info here: http://www.ispindel.de/docs/Kalibrierung.html) - upload on the nodemcu - additonaly you can use the thingspeak app for your cellphone Done and hve fun! About the code: I included the function to test it with delay and serial monitor in dry environment. The code you will find first is for uploading data to thingspeak. For more information, feel free to ask.
