Some problems with PMS5003 on pico-enviro+

Support
1

Hello,
I am a beginner with raspberry pi pico. I have bought with my raspberry pico an enviro+ card and a PMS5003 PM detector.

I can manage my enviro+card with the raspberry pico in many functions as displaying temperature, RH, atmospheric pressure.

I encounter two problems :

  • the card enviro+ can’t connect to my WiFi box (Orange box) but i haven’t work on it a lot so i don’t ask help for the moment :)
  • the card enviro+ and micro-python can’t see the PMS5003 :

Traceback (most recent call last):
File “”, line 10, in
ImportError: no module named 'pms5003

the beginning of my micro-python code is :

import time
from machine import Pin, UART
from picographics import PicoGraphics, DISPLAY_ENVIRO_PLUS
from pimoroni import RGBLED, Button
from breakout_bme68x import BreakoutBME68X, STATUS_HEATER_STABLE
from pimoroni_i2c import PimoroniI2C
from breakout_ltr559 import BreakoutLTR559
from adcfft import ADCFFT

comment out the next line if no particulate sensor

#from pms5003 import PMS5003

If i uncomment the last line i have the error quoted before.

I have tried many firmwares like :

  • pimoroni-picow_enviro-v1.19.10-micropython-v0.0.9.uf2
  • pimoroni-picow_enviro-v1.19.12-micropython.uf2

or other versions of these firmwares. Of course my PMS5003 is well plugged to the enviro+ card => Pico Enviro+ Pack

I will be pleased to have some help ;)

Regards
William

You just need to add the module for PMS5003 copy it onto your pico and then the import should work.
