Dust Sensor - PMS 5003/6003/7003


#129

Has anyone compared the readings from the SPS30 and the Honeywell HPM?

Thanks everyone for your input, I’ve enjoyed following this thread!


#130

Got it. Thanks Rftop.

I am working with the WEB IDE on the photon device. So how do you view the data out of the Serial1?

Also, did you need to an external 5V power source to power on the SPS30 sensor?


#131

The Photon reads the SPS30 sensor over it’s Serial1 interface (TX and RX Pins).
In the library’s example ino code, results are sent to the Serial interface in the Serial.print statements.
(Serial = USB; Serial1 = TX,RX Pins connected to the Sensor)

If you are connected to the Photon via USB, open your favorite Serial Monitor to view the results of each Serial.print.
You may already have the Arduino IDE installed, which has a Serial Monitor.
You can use Particle’s CLI if you have that installed. From a command prompt type: particle serial monitor --follow

I powered the SPS30 with the Photon’s Vin Pin. The photon was powered w/ USB.

@Rftop FYI the guy who created the library for the dust sensor just sent me a email saying he added the Air Quality Index feature to the code if we want to try it.

Let me know if you try it out.

Just completed an AirQuality Index library that works with an SPS30 for different regions. It is example 10 and needs a seperate library to be downloaded https://github.com/paulvha/airquality.

I have designed and tested only on ESP32 as needed enough memory, as well as a board that does NOT reset when a serial monitor is connected. Not enough knowledge about the boards you use.

Thanks for the info @RWB, I’ll give it a test drive :crossed_fingers:

Hello,

I am new to the boron platform and trying to run the SPS30 with Boron LTE firmware 0.9.0 (Using UART).
Trying to run the https://github.com/paulvha/sps30 code, its not getting complied. not able to find file ParticleSoftSerial.h in particle workbench looks like the library doesn’t support boron.
Is there another library which works with boron?

Thank you.


#135

There currently is no software serial but you should be able to use the HW interface Serial1.


#136

Hello @Rftop,

I am working to get the Boron to work with sps30 using UART.
Would it be possible for you to share how you did it ?


#137

@Pinak, I have not tried the recent versions of the Library.

What I did for V1.0 on a Photon:
Created 2 new “tabs” in my WebIDE project and copied SPS30.cpp and SPS30.h from Github.

I used one of the Example .ino’s with :

SYSTEM_THREAD(ENABLED)

#include "sps30.h"
#define SP30_COMMS SERIALPORT1
#define TX_PIN 8
#define RX_PIN 8
#define AUTOCLEANINTERVAL -1
#define PERFORMCLEANNOW 0
#define DEBUG 0
SPS30 sps30;

The Library is documented well.


#138

Hi. I am having trouble using the files from the github (https://github.com/paulvha/sps30) with a particle electron using I2C. Could someone who has gotten it working on a particle device help me out and possible upload the files an includeable library like the one made for the SCD30?


#139

Welcome to the Particle community.

I’ve had better luck using the SPS30 with UART than with I2C.

I’ll try to post my modifications to the library and a test app in the morning.


#140

FWIW the HPMA115S0 is a decent dust sensor. The PM10 usually aligns with what the value of the PM2.5 value is. (I’ve never seen them diverge) It’s configured via UART. I posted about it here on the forum if you need a good starting point.


#141

any update on that library?


#142

Wow. What you’ve done here is great with the visualization, etc. This is precisely the application I am looking at this sensor for as well (shop readings).

@RWB Have you posted about your project separately? Could you walk me through it?
I understand your SPS30 reports data to the Photon over UART…but how are you getting it into the Losant?

What’s a good, cost responsible place to publish data from a device like this?


#143

Losant is good but in my instance I cannot get what I need at a reasonable price. I have therefore used Thingsboard.io CE version (open source and free) on an Ubuntu 18.04 server on a simple low cost dedicated PC and have had great success. YMMV


#145

Losant’s free service has allowed me to do everything I have ever wanted for more than a year now. See if they still provide sandbox accounts and you should be good to go, I haven’t found anything else that is near as nice for no charge.


#146

@worldburger Grafana’s interface is pretty if you are looking for a free alternative. I know SORACOM has a “free” hosted version. (you need to use their data pipeline though :cry: )

I actually self-host my instance using InfluxDB as the backend. It’s been running since early April in one capacity or another. If you’re not afraid of a little bit of Docker dev ops you can get it up and running quick. Plus it integrates nicely with Particle Webhooks. :grin:


#147

Dear Eugene,

I red the forum and saw you got it working on a raspberry. Could you be so kind to share the code with me…there is limited documentation of the sps30 and python. I want to built this for our lab at the university of twente in Enschede, The Nederlands, as we are using fumed silica…

I hope you are willing to share the code,

Thanks in advance,

Kind regards,

Andries van Swaaij

Hi Andries,

I used the Sensirion sample implementation code from their Github. Here is what you need to do get it working on a raspberry pi running Linux.

  1. Pull the code from their repo:
    “$ git clone https://github.com/Sensirion/embedded-uart-sps.git
  2. Run: “$ make release”
  3. cd into the release directory and then replace the “sensirion_uart_implementation.c” file with the one in “sample-implementations/linux/sensirion_uart_implementation.c”
    “$ cd release/sps30-uart-3.0.0”
    “$ sudo rm sensirion_uart_implementation.c”
    “$ sudo mv sample-implementations/linux/sensirion_uart_implementation.c ./”
  4. Plugin the Sensirion SPS30 sensor using the USB cable from the dev kit into your raspberry pi. By default, it should appear under /dev/ttyUSB0 if you do not have anything else plugged into your USB ports of your raspberry pi.
  5. Compile the code
    “$ sudo gcc *.c -sps30”
    6 Run your program
    “$ sudo ./sps30”

This is what basically worked for me. Let me know if you any issues with the steps laid out above.

Thanks,

Eugene


#149

Hi, I am new to Particle devices and I am working with the PMS 5003 sensor on Boron and trying to output air quality values on my computer from Workbench. I have tried to run several of the codes from this thread on my computer but there were none that have successfully worked for me.

I decided to just go back to the basics and obtain raw data values and move forward from there but I am not sure what the next steps are.

//Just Reading Bits From the PMS 2.5 5003

SYSTEM_MODE(MANUAL);

//int PMSsignal = D10; //voltage signal from PMS
int val = 0;

int analogValue = 0;    // variable to hold the analog value

int incomingByte = D10; // for incoming serial data

void setup() {
	Cellular.off();
  Serial1.begin(9600); // opens serial port, sets data rate to 9600 bps
}

void loop() {
  // send data only when you receive data:
  if (Serial1.available() > 0) {
    // read the incoming byte:
    incomingByte = Serial1.read();

    // say what you got:
    Serial.print("I received: ");
    Serial.println(incomingByte, DEC);
  }
}


This rudimentary code reads out a series of 5 raw values every second I was wondering if you have an idea on how to proceed from here or helpful pointers on some code I may have missed along the way. It seems that Photon/Electron codes from previous posts do not work with Boron if I am not utilizing the internet/LTE features. Thanks for your support!
