So i bought a nova pm10 air quality sensor. It says it has digital output. I assume that chip converts the analog data to digital?
However i don't know how can i see the values? If i just plug in the usb to my laptop nothing happens.
Maybe any suggestion as to how is it done?
Or should i connect the pins from the sensor to the arduino and read the data off there? Ground goes to ground, 5v to 5V, but where would i connect the RXD and TXD(from sensor) to the arduino?
Any kind of help is appreciated!
