PWM modulation, in order to simulate the functionality of an electromechanical
pressure sensor. 43 Hz means 0 mbar, while at 38 Hz the pressure is 30 mbar.
Zero offset
The zero offset is a way to set a pressure (and temperature) reference before filling the
container with the liquid. In the demonstration board, this operation is performed by
pressing a button. Once the button is pressed, the pressure measured at that moment
is considered as 0 mbar. In a real application, there is no such a button to press; the
zero reference is set by the main MCU through a dedicated software routine.
STM8S103F2
The entire process is controlled by a 20-pin, 8-bit STM8S103F2 microcontroller. The
code size of the firmware is below 2 Kilobytes.
