Power hungry little buggers they be , they are drawing 250 mA plus in pulses every 100ms I'm told that's why the FTDI cables cant support them properly and that's also a likely cause of resets.Yes, I hope I have cured that issue now - see my earlier post.

I bought these. I don't know if they are originals or clones. Also I'm no expert on these sensors. I have used DHT11 in the past and the SHT21 seems considerably better, plus it has the i2c interface.
