Dht.h Library Download !FULL!

I am having trouble getting the DHT library to install (used for the DHT11 temperature/humidity sensor). I have downloaded the library shown in the attached image. However, whenever I try to include the library, I get the error message shown below. Furthermore, this library shows up under "Recommended Libraries" in my Arduino IDE as opposed to "Contributed libraries". Does anyone have any suggestion as to what is happening?

Otherwise, post a link to where you got the library. Post a link to where you got that code. Post the code that generates those errors. Please read the forum guidelines to see how to properly post code and some information on making a good post.

Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

DHT Library: GitHub - adafruit/DHT-sensor-library: Arduino library for DHT11, DHT22, etc Temperature & Humidity Sensors (this one was included with the original Project, so it should technically be compatible with the code)

I must be doing something very obviously wrong but I just do not know what

can anyone help please?

PS the same library and the same board and code works fine on the Arduino IDE but I really would like to continue using your new platformio.

I have also tried with lower case letters, but it will not work. Is there any reason why? Do I have to install it? I have tried to search for the library in the Arduino app Sketch - Include Library - Manage Libraries, but the library is not there.

You need to install the Adafruit Unified Sensor driver library. In your Arduino IDE, type in the search box Adafruit Unified Sensor, scroll all the way down to find the library and install it.

Writing the code to get temperature and humidity is also simple thanks to the DHT library. Getting temperature and humidity readings is as simple as using the readTemperature() and readHumidity() methods.

NaN stands for "Not a Number". Sometimes the sensor fails to read and gives you a nan value. You can't do anything against it, but in the DHT.h library is a function called isnan(). So you can make a backup variable were you store the last value that was correct. Then you can check if your sensor reads nan and if he does you can print out the backup variable:

I found out that if you ask 2 or more readings too fast (in my case, I was just asking for temperature) without a delay between two dht.getTemperature(); or two dht.readTemperature(); depending on which library you are using, the second one and the following readings will give you a nan (not a number) value until it comes back to the wanted readings again, and so forth. So I put a delay of 2 seconds (delay(2000);) between readings and it solved my problem.

I am installing Arduino IDE in a new PC and uploaded a code with DHT sensor that was compiled and working in another PC. The same happens with your DHT11 scketch code.

In this new one when code is compiled I received many erros specially saying that DHT.h does not exists.

I tried many different DHT libraries, for github ( -sensor-library) and from Arduino webpages and others that I found but no one worked.

The Adafruit library is the one that I use (but there are MUCH better sensors than any of the DHT range).

However, it also requires this library to be installed:

GitHub adafruit/Adafruit_SensorCommon sensor library. Contribute to adafruit/Adafruit_Sensor development by creating an account on GitHub.

In any event I did a file compare on DHT.cpp that is used for the arduino and the DHT.cpp that is available in the Particle IDE library and they are identical! That is the one that WORKS for the Photon.

Hallo TechPonder. I've typed the code and used the Adafruit DHT library. Downloading it went succesfully and got the circuit to work. Some other time when I wanted to use another DHT library from the GitsHub, it then shows an error that there is no such file as #include

// Initialize DHT sensor.

// Note that older versions of this library took an optional third parameter to

// tweak the timings for faster processors. This parameter is no longer needed

// as the current DHT reading algorithm adjusts itself to work on faster procs.

DHT dht(DHTPIN, DHTTYPE);

Reading the library code, you can enable debug statements from within the library. Uncomment DHT_DEBUG in DHT.h, and change DEBUG_PRINTER to the serial port you are using (Serial0 or Serial2 with your USB/Serial converter).

To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder DHT. Check that the DHT folder contains DHT.cpp and DHT.h. Place the DHT library folder your /libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.

The older library fixes the issue for me I think it has something to do with OMG. I also tried my ESP32 with OMG and I got the same wrong readings (dht library 1.4.4 and unified sensor 1.1.6). Using the same libraries (and versions) and the sketch I referred to earlier I got the correct values.

Once you have the "Arduino_Uno_Serial" example opened go to Sketch-> Include Library->Manage libraries. In the library manager search "DHT sensor library", once it comes up click on it and then select the install button that pops up. After it is installed restart Arduino IDE and then reopen "Arduino_Uno_Serial"

I had solved the problem by increasing the stack size to 400 (at least). Check the unused stack and adjust it to your need.

Also, it is better to update the DHT library and (not required) replace the delay() function in it by vTaskDelay().

For example, the library that provides the CayenneParsePayload function/method/class may not be required for all programs, so not linking with it works just fine in those cases but causes problems for programs that need it.

Why did I clone this library instead of forking the original repo and push the changes?When I searched through Github for DHT libraries, I found a lot of them, some of them offers additional functions, some of them only basic temperature and humidity values. I wanted to combine all interesting functions into one library. In addition, none of the DHT libraries I found were written to work without errors on the ESP32. For ESP32 (a multi core/ multi processing SOC) task switching must be disabled while reading data from the sensor.

Another problem I found is that many of the available libraries use the same naming (dht.h, dht.cpp), which easily leads to conflicts if different libraries are used for different platforms.

For manual installation download the archive, unzip it and place the DHTesp folder into the library directory.

In Arduino IDE this is usually **``/libraries/``*:raw-html-m2r:`

`In PlatformIO this is usually ****_

To get DHT22 to work, you just need the DHT22 library:

-sensor-library

and it requires a spare GPIO pin. On OpenGarage, GPIO 4 and 5 are spare pins and are mapped out, so you can use either of them.

Alternatively, there are I2C versions of DHT22 (for example, AM2320). GPIO 4 and 5 happen to be the hardware I2C SDA and SCL pins respectively, so you can also use AM2320. The library for AM2320 can be found here:

I have managed to get this display to work very well with several ESP32 boards using the library (which does not compile for the NANO) so I know the display is good. What I want to do now is to use the display with an Arduino Nano project I am working on but no joy.

Well, after many days of pulling out my hair I managed to discover a different library to use with my 1.3 inch display and the Nano. I have downloaded U8G2 which so far allows me to display 6 rows and 21 columns of text at the libraries default settings. One interesting problem with this library is text has to start not at the 1st pixel position (0,10) but at the 3rd pixel (2,10) as seen here:

I am very new to Arduino and was having difficulty with my 128x64 display. I too discovered the U8G2 library, which I find very easy to understand and use. However, I was not paying attention to one aspect of the constructor: U8G2_SH1106_128X64_NONAME_#_HW_I2C u8g2(U8G2_R0)

The platforms mentioned above as supported is/are an indication of the module's software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

This Grove - Temperature&Humidity Sensor and our another product Grove-Temperature&Humidity Sensor pro are sharing this library. No matter which product you are using, make sure that you have made the definition line of the sensor of your board into effect and commented out the definition lines of other specs. For example, the sensor we used on Grove - Temperature&Humidity Sensor is DHT 11. So the definition part of the sensor spec should be:

The Adafruit's DHT library for the DHT11, DHT21 and DHT22 temperature and relative humidity sensors has been adopted for the GR-Sakura board. These sensors use a non-standard 1-wire communication protocol, which is handled by bit-banging and sofware timing. The '1'-s and the '0' can be distinguised by measuring the data pulse lenght. The biggest difference between the Sakura and Arduino cards is the speed factor: the overhead time spent in the main cyle (when 40 data bits from the sensor are read) is much bigger in the case of the Arduino, which should be taken into account. This means, that the default parameter value used as "discrimination level" is too low for the Sakura board.In order to determine the optimal value of the "discrimination level" the debug features of the original test program were extended. 2351a5e196
