Hi everyone,
I'm doing the project that used humidity sensor to control speed of the fan that depend on humidity. Right now i'm facing the problem to use the humidity sensor HS15p and to display the humidity on lcd Display. I'm using pic16f877 for this project.
I didn't know how to make a connection between the sensor and pic. i've gone through one circuit and it said I must connect the sensor in series with resistor and it use three pin on the pic. I've tried but the sensor isn't working at all. Anyway at which part should I supply the the ac voltage since the connection i've got did not show the connection for ac supply?
Please help me and your answer are much appreciated. My email add: [email protected]
