SBL4TILT - "Sound Bubble Logger and Temperature controller for TILT" (ESP32 - TILT repeater, BPM logger and temperature controller).).

[kbaggen]

Dear All,
from my Bubble-logger project I have created the "SBL4TILT" project there is combined TILT repeater, but also a temperature controller and hence make use of the repeated TILT temperature to control a 2-channel relay. Furthermore, it logs airlock bubbles by digital sound sensor and reports BPM (blops pr. min) and "Sum BLOPS(pt)/L". Last but not least, SBL4TILT, easily take care of sending data till Ubidots, Brewfather and Brewersfriend (the last one I dont use so this part is very much beta). It is easy to build.

Picture from last brew: Brewfather
(A better picture will come)

Hence, this project measure/do:

1. Measure the activity of the yeast as CO2 escape the fermenter by a digital sound detector giving blops pr. min (BPM) and Sum BLOP(pt)/L). The Sum BLOP(pt)/L is the sum of Blops corrected for prressure and wort temerature impact on the bubbling rate and as it is corrected for brew size too, it is hence a comparable number from brew to brew (based on same calibrated sensor, aligment, water amount, airtight fermenter, excact known brewsize, etc.).
2. Repreats temperature from TILT into cloud
3. Rereats gravity from TILT into cloud
4. Hence, Send all data to the cloud in a easy way (BPM, Sum BLOP(pt)/L, Temperature, Gravity and color of TILT in use). The software sends to Ubidtos, Brewfather and Brewersfreind if you enter the url or Token in captive portal mode.
5. Estimate of “reduction in gravity” (rG) can be calculated from the Sum BLOPS(pt)/L based on complex model taking pressure and temperature data into account. In this way the Bubble-Logger emualted a PLAATO, but need user interaction for creating polynomial to translate into a real SG estrimate.
6. A 2-channel Relay to control a heat and cool source based on the temperature reading of the TILT every 2 min, hence, slow-working heating actor should be used.

Needed parts and Pin/pinout
It needs an ESP32 devkit, Sound Sensor Detecting Module LM393 and a 2-channel relay. Some 3 pins wires and some 2 pin wires is also needed.

(A "light" version whit no relay part and hence only sound sensor at PIN 13 is comming too, and hence will be a good choice to build as a start)

• heating: RELAY0_PIN 26 --> int1 on relay
• cooling: RELAY1_PIN 25 --> int2 på relay
• Soundsensor is connected on PIN 13
• 5v by ESP32 WIN
• Ground

Installing/Burn
Please use Brewflasher! "Sound-Bubble-Logger-and-Temperature-controller-for-TILT" should be an option to burn though Brewflasher. Release Improved ESP32 Support · thorrak/brewflasher

Thanks to "Thorrak" for adding this project till Brewflasher and for providing such an easy tool for DIY projects.

Your github links are broken. Looks like you copied the whole line (starting with Full/more) into the URL

rsquared, thnaks! should be corrrected till: https://github.com/kbaggen/Sound-Bubble-Logger-and-Temperature-controller-for-TILT

BTW......this have been updated a bit till v1.2 and most issues has been removed!
