MPXV7002DP is analog sensor which measures differential pressure and requires 5V supply voltage and gives an output voltage of 4.5V. However, I want to get the digital output so I will connect the sensor to ADC( MCP 3008) which is thus connected to Pi 4.

My only concern is if I will need a voltage regulator as Raspberry Pi pins are only 3.3V tolerant. Any suggestions?

  • You run an unnecessary risk by connecting 4.5V output to a GPIO input. It should be limited to 3.3V.

Use a resistor divider between the MCP3008 Dout pin and the Pi GPIO MISO pin.

Or buy a level shifter chip/module.
