    humidity sensor shtxx

    Use Sensiron SHT11 digital humidity sensor
    with the following features :

    * 2 sensors for relative humidity & temperature
    * Precise dewpoint calculation possible
    * Measurement range: 0-100% RH
    * Absolute RH accuracy: +/- 3% RH
    * Temp. accuracy: +/- 0.4C @ 25 C
    * Calibrated & digital output (2-wire interface)
    * Fast response time < 4 sec.
    * Low power consumption (typ. 30 W)
    * Low cost
    * Designed for high-volume applications
    * Leading CMOSens Technology for superior long-term stability
    * Very easy-to-use due to calibration & digital 2-wire interface

    The C source code for driving SHT11 :
    Sample Code humidity sensor SHTxx orginial c file (ZIP Version)

    hs1101 appliction c51 code

    Please take a look at The SHT1x / SHT7x Humidity & Temperature Sensor data sheet for more information.
    The circuit to connect SHTx to a microcontroller just like this :

    interface tmp36 to pic18f

    If yours controller has analog inputs, you can use much cheaper HIH3610 for humidity (connects directly to ADC channel) :
    http://www.aagelectronica.com/pdf%20docs/hih3610.pdf
    http://www.phanderson.com/hih3610.html
    http://www.phanderson.com/picaxe/hih3610.html
    and DS18B20 (digital), or TMP36 (analog) for temperature measurements
