I recently connected the Nova PM sensor, SDS011 (pictured) to one of the USB ports on my Raspberry Pi3.
I have added the following data to the sensors section of my configuration.yalm file
- platform: serial_pm
serial_device: /dev/tty.SLAB_USBtoUART
name: Nova
brand: novafitness,sds011
I have restarted my RPi3 and this is the error message that appears:
Could not open serial connection to /dev/tty.SLAB_USBtoUART ([Errno 2] could not open port /dev/tty.SLAB_USBtoUART: [Errno 2] No such file or directory: ‘/dev/tty.SLAB_USBtoUART’)
Does anyone know what I’m doing wrong?
Considering the price, in my opinion, reliability is acceptable.
I have encountered two problems.
Sometimes (2 or 3 times a month), it seems as if the buffer gets stuck and then suddenly releases the contained data. With that 200 and 300 ppm data, we should be dead.
At high relative humidity percentages, the laser identifies some droplets as particles and slightly increases the measurements.
