Need Someone for a Project: Cypress PSoc6 BLE kit +  Honeywell Pressure Sensor Shield

rscasny

I was contacted by a supplier who is interested in giving hardware for free to someone who could do a project for them featuring  Cypress's PSoc6 BLE kit +  Honeywell Pressure Sensor Shield.

 

They would like the person to do the following:

 

Interface the pressure sensors of the Honeywell Sensor Shield with the PSoC 6 analog/digital peripherals and then transmit data via BLE or showcasing it on the E-ink display of the PSoC 6 BLE Kit. The project should have some kind of medical application. For example, measuring pressure in some kind of health/medical application.

 

Just to refresh your mind, here are the parts involved:

Click here for more information on this Honeywell Sensor Shield. I have not roadtested this product.

 

I would like to do this sometime in October. I'd like to get it accomplished in a month--the shorter time period is why I am not offering it as a roadtest.

 

If you are interested, feel free to comment below.

 

thanks.

  • re: breakout boards

     

    I spoke with our sales manager. Doesn't look like the breakout boards are available yet.

     

    I'm placing the sensors part order now. I'll keep a watch out and if they come available, I'll order and send them to you.

    Hi Randall

     

    Well, I found a breakout board that looks good for the project.
    I found one at Adafruit that has the same MPRLS sensor and voltage regulator as well as a level shifter for the data signals on board.
    I would use this as "hello world".
    Because a voltage regulator and level shifter are included, it is easier to use than Honeywell's breakout board.

    Is this a problem to can get one as a sample kit? If not, no problem.

     

    At the Attachment there you can find the schematic and PCB for Eagle CAD.

    I thought as well for the others whether they need this.

     

    Best Regards

    Gerald

    Adafruit move fast! Yesterday, when I checked they were out of stock but I see that they have a fresh batch in.

     

    Worth noting that the Adafruit option uses a 25PSI max MPR sensor which takes absolute measurement, so you would have to bear in mind that atmospheric pressure is included in the reading rather than excluded as per gauge type measurement.

     

    Also worth noting is the use of a 1nF cap between VO+ and VO-, and the 0.1uF bypass cap tied to Vdd on the Adafruit breakout. I see that the 0.1uF cap is already included in the schematic of the SEK002 board but not the 1nF.

     

    Anyhow, I agree, the Adadfruit breakout is useful just for an initial "hello world" test. So I'm happy without it.

    The PCB has a hole for the sensor with gauge. You can change the sensors, mounting absolute or relative.

    VO+ and VO- just are used if you want to do something with this. Normally i use the digital output.

    I think this board is relative flexible to use the sensor's functions.

    Yes, "hello world" tests is what i wanted with this.
