The change in resistance between the two electrodes is proportional to the relative humidity. Thanks in advance, Ethan. Anyone have thoughts about this? Marc Remmerie on January 6, at 4: What might i be doing wrongly, I have even tried the code that accompanies these tutorials Reply.

Probably not, since the signal is at the same voltage as Vcc. I get this same dytlib when I try to use the Arduino instead of the Uno.
Relative humidity is the amount of water vapor in air vs. What is that Ic used to send data to the arduino …. I need full code of the sensor connected to LCD Reply.
I will be experiencing a few of these issues as well. Thanks in advance, Ethan. I can not keep my display from blinking the temp and humidity values.

How to Set Up the DHT11 Humidity Sensor on an Arduino
Dale Bridgford on January 10, at I found this article to be a whole lot clearer and easier to understand than most, but I do have a few points.
Syaz on March 25, at 9: LM on September 10, at 1: Dhtllb Jose, you can definitely connect more than one sensor to a single Arduino.
Jake Jordans on January 23, at 2: Hi, Is there a way to send alerts to an email dbtlib if the temperature and humidity is above a certain value? If i want to mix lcd,dht 11 and heater for use arduino? Is there a way to change it from Celsius to Fahrenheit Reply. I copied this exactly and got it to display temperature and humidity, but it flashes for temp and for humidity every other second.
I got the same readings alternating with good readings. Rok on December 28, at 8: Michael Atencio on June 13, at 9: The code below is the bare minimum needed to initialize the sensor. Something wrong with this page? When I originally commented I appear dhflib have clicked the -Notify me when new comments are added- checkbox and now whenever a comment is added I receive four emails with the exact same comment.
God bless more power. Please write to the free places for accommodation, their formats and cost. Twl on December 30, at 9: Thanks for the tutorial dude.

Please try to be generic in your improvements and try to see "over the needs of your own application".
