CubeCell HTCC-AB01 and device 5V

ivanvirtuale · January 26, 2022, 11:55am

Hi folks…
I have to connect a MPX5100DP that is working only 5V. What’s the cleanest way to do the job ? a level shifter and a step up ? Or what ? Please advices

Some help please ? Tell me what’s the best way … or what’s wrong!

best way is a level shifter of course…
but you would still need to provide a power source for the 5v from somewhere…
maybe the driver below can help, it shows a 3.3v reference so maybe it does work with 3.3v

here is a driver:

github.com

DouglasUrner/Arduino-MPX/blob/master/MPX5xxx.cpp

/*
** Driver for the Freescale MPX5xxx family of pressure sensors.
**
** Tested on:
** - MPX5010 (10 kPa)
** - MPX5100 (100 kPa)
** - MPX5700 (700 kPa)
*/

#include "MPX5xxx.h"

MPX5xxx::MPX5xxx(byte devType, byte pin)
{
  _devType = devType;
  _pin  = pin;

  analogReference(DEFAULT);
}

MPX5xxx::MPX5xxx(byte devType, byte pin, byte refType)

Hi, I had the same problem with the SDS011 sensor (5V) and I use a boost converter, see: https://raw.githubusercontent.com/CargoBikoMeter/LoRaWAN-Solar-PM-Sensor/main/images/LoRaWAN-Solar-PM-Sensor.svg
