 Hi, i have a problem with my DHT11 sensor, it always showing 95%(maximum)humidity(the temperature is showing correctly). I have the one on a PCB with the pull up resistor already on. I have connected to the arduino digital pin 2 and i am using the adafruit library for DHT sensors. i ran the example code, selected the DHT11 sensor and the temp is equal to my room, but the humidity is at 95%(maximum). First time i ran the code is worked perfectly, until the humidity slowly climbed to 95%. I switched the sensor with another one and still the code ran prfectly(15-20mis) until i experienced the problem again. I switched back to the first sensor and it happend the same thing. Any ideas?

Hi,
What is the humidity in your room?

Have you taken it out doors whee hopefully the humidity is lower?

Can you post a picture of your project so we can see your component layout please?

What part of the world do you live?

Thanks.. Tom... :)
Everything runs on smoke, let the smoke out, it stops running....
