adding rs485 device to B16M

[beon intelligent]

how can i connect this sensor to use rs485 on a B16m

[admin]

what problem now? can't read temperature value on "Monitor" webpage?
you can use USB-RS485 adapter to read the sensor data firstly, if the address is correct confirmed, then add to B16M set by KCS webpage.

here is details and pc software download link: https://www.kincony.com/tiny-sht30-tempe...ensor.html

Hi Beon.  Thank you for your pictures.
I wanted to mention about RS-485.  It is a differential pair of wires.  You can look that up e.g. in Wikipedia.
So that you don't end up with too much DC bias on the pair, it's usual to twist the pair of wires, especially for higher speeds and longer runs.  Then any voltage induced on the wires affects both wires, since both wires are alternately closer to the noise source.
You have used twisted-pair wires, but you put both wires of the pair into one terminal.
For real-world use you should open up the twisted pair and put one conductor into each of the A and B terminals.
With Ethernet cable as shown, a single pair like that can be a bit fragile (you can get industrial wire for RS-485 but it's really expensive).  You could use two pairs.  In comms language, the wires are the colour and its "mate" (the white wire twisted with the coloured wire).  Open up both pairs and twist the whites together and the colours together.  That makes a stronger job and it's balanced.
Regards,
Kevin.
