DHT11 Humidity and Temperature Sensors
DHT11 – Humidity and Temperature Sensor for Arduino and B/B+/2.
The four-pin device uses a 1-wire protocol. 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.
