Interfacing humidity sensor sy-hs-220 to adc

[hardeep]

I want to interface humidity sensor module to adc of atmega 16 and i want to take 50 readings and average the readings then compare with a reference value and take the respective action….plz help in coding,,,i am using codevisionavr as the programming software…

the humidity sensor gives the percentage humidity.take the percetage of received value considering 1023 as 100% humidity.

Hello sir…

im a final year BE ECE student .i hav selectd my project to be

 

AGRICULTURE BASED WET AND DRY CONTROL FOR PUMP FROM REMOTE DESTINATION… using PIC microcontroller.how to couple humidity sensor of soil to MC.&how  can i couple the  MC to a GPS modem?where can i get the coding related to it?/..please giv info as soon as possible sir…

Srikantgh,

Humidity Sensors are widely available in the market, you can get it in electronic stores at a price of 250INR, you can directly interface humidiry sensor to PIC controller ADC.

plz send me circuit diagram of gsm based irrigation system

[dheeraj]

which humidity sensor in used in the 8051 interfacing project and what is the price of humidity sensor? please tell me as early as possible.
