Unable to fetch data

[jjj5313]

Hi. i am new to home assistant. i have been trying using pms5003 in my setup. However, home assistant unable to fetch data from sensor.

it is like: 2017-05-20 13:56:36 ERROR (Thread-9) [homeassistant.components.sensor.serial_pm] Could not read PM10 value 2017-05-20 13:56:38 ERROR (Thread-4) [pmsensor.serial_pm] read timeout after 2 seconds, read 0 bytes 2017-05-20 13:56:38 ERROR (Thread-4) [homeassistant.components.sensor.serial_pm] Could not read PM1 value 2017-05-20 13:56:40 ERROR (Thread-1) [pmsensor.serial_pm] read timeout after 2 seconds, read 0 bytes

Is there anything wrong with the code? Thanks

This simply means that the code can't read data from your sensor. Try to connect directly via a serial terminal and check if you get data back.

Can you please tell what is the unit for the values we are getting?

Date_Time	PM1	PM2.5	PM10
2019/02/14 09:52:35	260	2854	3936

I am getting this kind of output

Thankyou.
