Hello everyone, I am working with a raspberry pi zero 2W running on bullseye OS with the enviro+ and PMS5003.
Everything except for the particle sensor is working, whenever I try to run particulates.py the following error message pops up:
Traceback (most recent call last):
File “/home/pi/enviroplus-python/examples/particulates.py”, line 18, in pms5003 = PMS5003()
File “/usr/local/lib/python3.9/dist-packages/pms5003/init .py”, line 109, in init
self._pin_enable, self._pin_reset = gpiodevice.get_pins_for_platform(PLATFORMS)
ValueError: not enough values to unpack (expected 2, got 0)
As some users suggested in other topics I downgraded to version 0.0.5 via “pip install pms5003==0.0.5”, but by doing that I get the following error:
Traceback (most recent call last):
File “/home/filip/Pimoroni/enviroplus/examples/particulates.py”, line 24, in
readings = pms5003.read()
File “/home/filip/.local/lib/python3.9/site-packages/pms5003/init .py”, line 127, in read
raise SerialTimeoutError(“PMS5003 Read Timeout: Failed to read start of frame byte”)
pms5003.SerialTimeoutError: PMS5003 Read Timeout: Failed to read start of frame byte
Is there any known issue with the OS or with the board / phat combo that could solve this issue?
Thanks in advanced
