The boards seem hastily assembled, on one of them someone even forgot to cut the sensor pins after soldering. The resistor in all of them had a 102 (1k) code, not 472(4.7k) like in the pictures. Other people have mentioned this, be careful with the pins - is ground, S is data and the middle one is power (+5v). All five sensors worked, you can tell it is being accessed when the LED lights up. II also tested one in parasite mode and it worked, however the LED doesn't light up in this mode.

The pinout on these is not what you might think. If holding the board with the pins facing you and the device on top and furthest away from you, the left hand pin is GND, then middle is +Ve and the right is DQ (data). On my board the left hand GND pin is marked as '-' and the DQ data pin is marked as 'S' The onboard LED is between DQ and GND and hence flashes when the board is accessed. Don't forget a pullup resistor of 4K7 is required between +Ve and DQ. You only need one regardless if how many sensors you connect in parallel.
