Re: How to connect 2 I2C and SPI device to a single pro mini

Hello,

I am currently working on a project with a pressure sensor : DLVR SERIES LOW VOLTAGE DIGITAL PRESSURE SENSOR (DVLR-L60D). Can you please tell me how to connect this with an arduino pro mini 3.3v .

Thank you

  1. Don't hijack old topics, start your own.
  2. Post a link to DLVR SERIES LOW VOLTAGE DIGITAL PRESSURE SENSOR (DVLR-L60D) so we can look at what you are asking about. http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjwtYnSn7vKAhWoyIMKHSRtA8UQFggtMAA&url=http%3A%2F%2Fwww.allsensors.com%2Fpress-releases%2FDS-0300_Rev_A13.pdf&usg=AFQjCNHhdlXf1BshaZgNeyZXy6RQd033kg&bvm=bv.112064104,d.amc This one seems to bring up a datasheet. For I2C, you connect to SCL, SDA, Gnd Power, and INT to D2 for example. Then find a library to read its data. "Supply Voltage Devices are characterized at either 3.3V or 5.0V depending on the options selected. It is suggested to select the option that most closely matches the application supply voltage for best possible performance." Do you have the 3.3V model? SCL/SDA are A4/A5 on the ProMini (or maybe A5/A4, I always have to look that up myself, you should too).

Hello,

I have the 3.3 V model for the sensor. and pro mini is a 3.3 V one too. I am confused about the connections. Could you please elucidate about them.

I am not able to find a link for the DVLR sensor. I could find only the data sheet which you posted. I also have a honeywell digital sensor (ABP-D-AN-N-005PG-2A3) which I am trying to connect it to a arduino pro mini. I am not able to find the data sheet/pin diagram for this one too. Could you please help.

Sorry for hijaking this topic. will start a new topic.

Thank you

Hello,

I have started a new topic " Connecting honeywell sensor to arduino pro mini"

Can you please help me with this.

Thank you
