PMS5003T not recognized #19

pczolee · 2021-02-01T12:45:34Z

Hello.

I try to use your program with a PMS5003T sensor. Unfortunately not recognized. Can you help me what should be the problem?

pms -m PMS5003T -s /dev/ttyAMA0 --debug info

The sensor itself working, because I testing it with this:
https://github.com/pjq/rpi

./monitor.sh

start monitor pm2.5...

Thanks

The buffer seems to be too long, as if your PMS5003T did not recognized the passive mode command.

Are you using the rpi's serial pins? Did you connect both RT and TX lines?

pczolee · 2021-02-01T13:21:53Z

Yes I'm using both RX and TX (and nothing else, just the power is connected).

I can not find a valid header/message on this hexdump.
Can you set the baud rate to 9600? I think the command is stty -F /dev/ttyAMA0 9600

Hmm, interesting...

Glad I was able to help.
Could you post the results of the following commannd line on #2?

pms -m PMS5003ST -n 10 -i 10 serial -f hexdump

I use sensor data captures on the project documentation and test suite

pczolee · 2021-02-02T10:39:03Z

Of course, I edited the command (because of the different com port):
