Hello,
I'm using a capacitive humidity sensor SY HS 230. I need help regarding the circuit connection of the same with ADC[0808] and then microcontroller[P89v51rd2].

Initially i used HH10D sensor which gave frequency as output. But now i have changed the sensor and i am not able to figure out the connection as well as the C programming[in keil] for the same [nothing much is give in the datasheet].

Please if anyone can help...need it as soon as possible for my project.
Thank you in advance!
 

The SY HS 230 outputs a voltage 0 - 5 VDC that is equal to o - 100 % humidity.
You must connect the sensor to an analogue pin of the microprocessor
You must do an A2D in the microprocessor on that analogue channel

Thank you for your response but i use an external ADC 0808 and then give those inputs to microcontroller.
Please if anyone can help regarding coding of the same in keil c compiler.
