I wanted to post an update to this.

First off: anyone who needs a PSoC 6 Pioneer kit, they are on their way to me. I got the tracking number so I should get them shortly. In addition, I have ordered 5 Honeywell Sensor Shields (SEK002) for all of you. Before looking at the datasheet, I casually assumed that the sensors were placed on the shield, as they are on other shields/expansion boards. After looking at the datasheet, I assumed incorrectly. I believe Enrico mentioned that too. So, I need to get some information regarding the sensors, etc. This is what is happening:

I will order everyone a micropressure sensor (MRP) series. But you have to tell me which one. So go here, and select the one that you need. If you don't need one, tell me that too:

ABP Series

Tell me which one you need from the ABP series: https://uk.farnell.com/search?st=honeywell%20abp

Humidicon Series

Tell me which one you need from this series: https://uk.farnell.com/search?st=honeywell%20humidicon

I'm not including the particle count sensors because I don't expect they are need for the medical application.

So look over these links and tell me which ones you need and I'll order them.

Hi Randal

I have a couple of queries.

Please could you check with Honeywell which pin is used as the select pin for the SPI sensors on the SEK002 kit. Documentation not clear. Images in documentation show an SS0 (Arduino pin 10) and an SS1 (Arduino pin 9). Reason being is that the PSoC 6 EPD Display Shield uses Arduino pin 10 as its SSEL pin.

Then wanted to check product codes and descriptions before ordering. Farnell order number 2773682 is listed as a differential sensor (ABPLANT015PD2A5) even though it is described as a single axial barbed sensor, which matches image. I always assumed that differential sensors require two ports.

Also, order number 2490463 is listed as a gauge sensor (ABPDRRT005PG2A5) and has two ports.

Thanks

Colin

Hi Colin,

The sensor ABPLANT015PD2A5 (2773682) look like this one:

The pinouts on the SEK002:

I think, its not so a big problem.

The device name code includes which interface the device has.

So for the both of your selected sensors ABPLANT015PD2A5 and  ABPDRRT005PG2A5ABPDRRT005PG2A5 they has an I2C interface with the address at 0x28

Hi Gerald,

Yes I have seen the tables, but they did not make sense at the time. But now seeing it again, it clicked and can relate to which header pins refer to P3 and which ones to P2. Not sure about "T1" though. This now confirms that there are clashes.

So for ABP digital SPI type sensors, the SS pins are all on the P3 header and these pins clash with EPD display shield pins (Border, Disch & EPD_EN pins).

For the MPR it refers to "T1" header which I cannot find shown anywhere on the SEK002 image. Any clues.

For HumidIcon sensors it refers to P2 and pin 1. Assume numbering starts at 1, then as per SEK002 board image, this is Arduino Pin 8, which is ok.

Of course, now scratching my head as to why they included SS0 and SS1 on the SEK002's silk screen.

Just found T1!

Hi Gerald

I was reading the Product Features list as per the html link you sent me. The first feature stated is "Measure gage and differential pressures".

Oh boy, now even more confused. Still cannot figure out how it can measure differential just within the one sensor port shown.

Hi Colin,

the sensor has a hole, on the bottom side. This is the gage reference hole to the input port.

The sensor measures the difference pressure. Please look to image above. There are drawings of the devices it shows this hole.

So if you builds you own PCB you have to know this, you need to make this hole also into the PCB.

Please read page 11:

I assumed that the gage reference hole (as shown on pg 11) was used to measure atmospheric pressure which is needed to provide a gage pressure measurement.

My earlier comments were based on the definitions given on page 2:

As such, I see a differential sensor as having two ports where you can apply pressures to. This allows you to measure the difference.

And so, sensors only having a single port can only ever be gage, or absolute, as your application can only apply pressure to this one port.

I see there also have a "no port" sensor option... hmmm. I assume that must be atmospheric only.

Yes, I read this last week and have had thinking the same about this….

hm....

Now I wrote to Honeywell an email to order the schematics about the SEK001 and SEK002, got now a ticket number.

Well I look forward hopefully to get one. I made the image to negative color so you can better see the wires.

May be this helps a little bit.

If don't get the schematics then I rework back, from PCB to schematic.

Best Regards

Hi Colin BigG ,

Now I have received the circuit diagram, which I would like to post here as well.
Now you can set the jumper settings correctly.

I am already curious about the reviews.

Best regards
