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.
Full/more info at: https://github.com/kbaggen/Sound-Bubble-Logger-and-Temperature-controller-for-TILT/
Picture from last brew: Brewfather
(A better picture will come)
Hence, this project measure/do:
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)
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.

Hence, this project measure/do:
- 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.).
- Repreats temperature from TILT into cloud
- Rereats gravity from TILT into cloud
- 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.
- 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.
- 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.
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
