This is he dust sensor serial port board – please notice the colour of the cables
And next up is a BUB/FTDI – a usb to serial port connector
the other end of this board has a USB female socket – use a USB cable to connect this to the raspberry pi.
Hi tor, I’d like to build a rpi-based PM2.5 portable dust unit. Which, in your opinion, is the most reliable/affordable sensor for this task?
Not sure I understand – as PM2.5 is the sensor – and I am running mine from a Raspberry Pi, posting to a number of cloud based databases and display services such as ada fruit.io.
