DHT.h files and other libraries are not available

[twinankhs]

Cannot get the download of DHT.h because the place to download the files is no longer online.
Can't compile because the packages do not include the DHT libraries

[twinankhs]

https://github.com/adafruit/DHT-sensor-library is where you need to link to in order to download - the main source repository is broken

Adafruit Sensor.h file is missing:

You will need to merge all of the libraries into one directory else arduino will not see the libraries - needs to be in one path with the DHT files and libraries.

Center Pin is the Data leg of the circuit, and the left and right are positive and negative, follow the board markings on the sensor not the manual. The yellow wire goes to the middle!

You actually should download both - you will sort of need to debug by putting everything into one directory seems to solve the issue. Then also copy it into a second directory to solve path issues depending on the product.

You will see the invalid library found debug messages in arduino when you go to upload it.

Sketch uses 6722 bytes (20%) of program storage space. Maximum is 32256 bytes.
Global variables use 219 bytes (10%) of dynamic memory, leaving 1829 bytes for local variables. Maximum is 2048 bytes.

// REQUIRES the following Arduino libraries:
// - DHT Sensor Library: https://github.com/adafruit/DHT-sensor-library
// - Adafruit Unified Sensor Lib: https://github.com/adafruit/Adafruit_Sensor

#include "DHT.h"

#define DHTPIN 2 // Digital pin connected to the DHT sensor

#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22 (AM2302), AM2321
//#define DHTTYPE DHT21 // DHT 21 (AM2301)

// Connect pin 1 (on the left) of the sensor to +5V
// NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1
// to 3.3V instead of 5V!
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor

// 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);

void setup() {
Serial.begin(9600);
Serial.println(F("DHTxx test!"));
