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: +/- 0.4°C @ 25 °C
* Calibrated & digital output (2-wire interface)
* Fast response time < 4 sec.
* Low power consumption (typ. 30 µW)
* 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 :

Thank's budhy for your reference, but the device may be need any circuit/driver?so coudl you to help me to find circuit/driver for this application(i hope you can give completely circuit/driver).
once again i'm many thank's to you for help me and coorporate.

humidity driver sht1x dewpoint calculation

Use the bridge configuration for humidity along with opamp and lm35 temp sensor.
 

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 :

keil hs1101 driver

Hi

humidity-sensors are SHT11 and HS1101

Ado
 

connecting hih3610 to avr

check 8052.com for code
