Gravitymon PCB for ESP32c3 Zero PET
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.
Note! In this version the R1 + R2 needs to be 10k not 220k as noted on the silkscreen. Next version of the PCB will have this corrected. Schema is updated.
Note! The pull up for the temperature sensor (R3) should be connected to 3.3V not VCC as in the layout. Using VCC might damage the ESP. Mount it between the inner hole and the 3.3V pin on the ESP.
