Hi guys !
I have ESP32 XIAO S3 SeeedStudio with a PMS5003 Air Quality sensor and I can't achieve to make it work. I have uploaded the test firmware only showing the values provided by the PM5003 but when I open Serial monitor , nothing shows.
I am powering up the PMS5003 with the Volts output from the ESP32 XIAO S3. My main power source is the USB Port from my laptop
IMPORTANT: If i remove the sensor and upload a new firmware only sayin: "Hello World" by Serial port, this show correctly the text. What could be the problem ? I dont have any other components connected to the board
