    • RE: PMS7003 Sensor - TTY/UART scrambled output [solved]

      Ok, you are right, the sensor it's working good, I just have to code to get the output.
      I've found https://github.com/rjaros87/pm-home-station on github, it has a windows app and i tested there.

      I found a Python script that output the PM2.5 and all for Python and I can use it with RaspberryPI - https://github.com/MarkJB/python-pms7003/blob/master/pms7003.py - Thanks @MarkJB (github)

      Can you set the thread to [SOLVED] ? Thanks

      @mfalkvidd I know that, but I should see 01010101 or [0x42, 0x4d] output not scrambled data

    • RE: PMS7003 Sensor - TTY/UART scrambled output [solved]

      I connected first time on the RaspberryPI UART and I get scrambled output, I thought that is something wrong with RaspberryPI UART and I've bought a CP2102 USB to UART Bridge Controller and I get the same output.

      The baudrate of the image that I shown is 9600 - this is the command that I use to get the output: screen /dev/ttyUSB0 9600 or cat -v < /dev/ttyUSB0

      Perhaps the sensor is broken? have anyone this sensor or PMS5003, what output do you get when use screen or cat?

    • PMS7003 Sensor - TTY/UART scrambled output [solved]

      Hello,

      I've bought a PMS7003 air sensor from alliexpress and I connected to RaspberryPI UART and I get scrambled output

      Any idea?

      Thanks
