Overview
The four-pin device uses a 1-wire protocol. [Rajendra] discusses the ins and outs of the communications, demonstrating the part using a PIC 16F628. It’s a snap to connect to your project, requiring VCC, GND, and a pull-up resistor on the single data line. We’ve already seen it used on at least one project, and hope to see more of this little guy in your own hacks.

Great!
These are excellent little units. I even accidentally reversed the voltage polarity and melted the casing... but when I fixed my mistake, it was still working!
They aren't super accurate, if you need something better go for the DHT22 or the BMP sensors
