This is a digital temperature and humidity sensor module that works with all of the Arduino micro-controllers. Because it is a digital sensor it only necessitates 3 connections, Vcc, GND, and a digital pin for data output. With this sensor, you get two measurements (humidity and temp) while only using one digital pin on the Arduino! This sensor would be perfect for creating an HVAC control system or for controlling something like a food dehydrator.

This humidity and temperature sensor is very popular and has an Arduino Library dedicated to it.
