Gravitymon PCB for ESP32c3 Zero PET v1.2
Oct 22,2025
Gravitymon is a electronic hydrometer software that can be used to measure gravity and temperature during fermentation of beer and report the progress to a number of external services. Is uses a gyro to measure the gravity since there is a correlation between gravity an the density of the fluid. Based on the density the hydrometer will float at a different angle. The graph below is an example on how the fermentation process can be tracked.https://gravitymon.com/In v1.2 the project is converted t...
