Needed pull-up resistor
Didn't work initially until I added a 10k resistor between data and VCC. Might be confusing for beginners.

Great for weather station
I used three of these for my backyard weather project. Consistent readings across all units.

Works perfectly with Arduino
Easy to wire up and the library examples worked straight out of the box. Readings seem accurate compared to my home thermostat.

Good sensor, slow sampling
Does the job well. Just remember it only updates every 2 seconds so don't expect real-time rapid changes.
