Connect SDS011 sensor to Cayenne [SOLVED]

skweresp · January 6, 2020, 12:21pm

YEEES!!! Now it works Thank You very much. You’re great!!!

shramik_salgaonkar · January 6, 2020, 12:22pm

you better start learning python language. You are just copy pasting what i am giving you which is really bad.

skweresp · January 6, 2020, 12:24pm

Yes, I will learn. First I learning Raspberry Pi and making simple projects.

shramik_salgaonkar · January 6, 2020, 12:29pm

wow, it like learning to make word without learning alphabet

skweresp · January 6, 2020, 1:50pm

I know I start learning with SnowPI gpio snowman [It’s possible to add him to cayenne?]

shramik_salgaonkar · January 6, 2020, 1:55pm

do you have any links to above?

skweresp · January 6, 2020, 2:09pm

I solder leds and download codes from github. Now I’m learning that codes and try to change them. SnowPI

Can You help me one more time? I cannot make my sds011 sensor work at start. I add to crontab -e:

@reboot cd /home/pi/ && ./aqi.py
@reboot python /home/pi/example.py &
@reboot python /home/pi/czujnik.py &

I also try

@reboot cd /home/pi/ && ./aqi.py
@reboot python /home/pi/example.py &
@reboot cd /home/pi/ && ./czujnik.py

do I have to delete file aqi.py from /home folder?

shramik_salgaonkar · January 6, 2020, 2:29pm

yes, you have to.

skweresp · January 6, 2020, 2:45pm

I delete aqi.py and delete entry from crontab. Still don’t want to start on boot

shramik_salgaonkar · January 6, 2020, 2:56pm

make it:
@reboot python /home/pi/api.py &

skweresp · January 6, 2020, 3:01pm

Still don’t work. My crontab file looks that:

@reboot python /home/pi/czujnik.py &
@reboot python /home/pi/example.py &

shramik_salgaonkar · January 6, 2020, 3:12pm

try this if you are using python3 to execute your script:

@reboot /usr/bin/python3 /home/pi/czujnik.py

skweresp · January 6, 2020, 3:26pm

python3 don’t work with that code.

shramik_salgaonkar · January 6, 2020, 3:34pm

with this crontab, try this and see the error in the log file

skweresp · January 6, 2020, 3:41pm

what I have to try?

skweresp · January 6, 2020, 3:43pm

I copy last lines from log:
