Abstract: A pressure sensing device includes a pressure signal receiver configured to receive an analog pressure signal from a pressure sensor, a converter configured to convert the analog pressure signal to a digital pressure signal, and a processor configured to convert a pressure value of the digital pressure signal to a bit value corresponding to the pressure value and output the bit value. The processor is configured to convert the pressure value to a first bit value by a first bit resolution in response to the pressure value being included in a first pressure interval, and convert the pressure value to a second bit value by a second bit resolution in response to the pressure value being included in a second pressure interval. The second pressure interval is a pressure interval greater than the first pressure interval, and the first bit resolution is greater than the second bit resolution.
