Humidity and temperature sensor
This is a simple breakout board for the SHT15 humidity sensor from Sensirion. The SHT15 digital humidity and
temperature sensor is fully calibrated and offers high precision and excellent long-term stability at low cost.
The digital CMOSens Technology integrates two sensors and readout circuitry on one single chip.

Another humidity and temperature sensor is the DHT11
Here is an example how to read this sensor with an arduino
This is the library you need. In the Arduino programming environment go to sketch/include library/Add .ZIP library to include this library.

And how to connect it to an arduino:
Do not swap + and - because this will destroy the sensor!
