Davide Gironi: Reading Temperature and Humidity on AVR

Wiring up DHT11 Temp & Humidity sensor to the Arduino
Wiring up DHT11 Temp & Humidity sensor to the Arduino DHT11 Temperature and Humidity sensor. The DHT11 is chosen because it is lab calibrated, accurate and stable and its signal output is digital. Most important of all, it is relatively inexpensive for the given performance.
How to Set Up the DHT11 Humidity Sensor on an Arduino
Wiring the DHT11 to the Arduino is really easy, but the connections are different depending on which type you have. in case of a 3 pin DHT11. the diagram above is not right. i was getting the same problem here. Reply. D R SOLANKE on February 22, 2017 at 2:26 pm . sir i m still getting -999 as temp and humidity aftr swapping both ways.
DHT11/DHT22 Sensors with Arduino Tutorial (2 Examples)
Wiring – Connecting DHT11 and DHT22/AM2302 to Arduino Uno. The wiring diagrams/schematics below shows you how to connect 3 or 4 pin temperature and humidity sensors to the Arduino Uno. A 10 kΩ pull-up resistor is needed between the signal line and 5 V to make sure the signal level stays high by default (see the datasheet for more info).

Insight Into How DHT11 DHT22 Sensor Works & Interface It
Wiring – Connecting DHT11 and DHT22 to Arduino UNO. Now that we have a complete understanding of how DHT sensors work, we can begin hooking it up to our Arduino! Luckily, it is trivial to connect DHT11, DHT22 sensors to Arduino. They have fairly long
Wiring DHT11, DHT22, with OLED Screen on ESP8266 12E
Wiring DHT11, DHT22, with OLED Screen on ESP8266 12E. Yet another illustration how to use the 0” OLED 128×64 Screen Display, and DHTXX Temperature & Humidity Sensor, The OLED 128X64 Screen Display module it is made of 128×64 individual blue OLED pixels,
Wiring | DHT Humidity Sensing on Raspberry Pi or
Wiring up DHT humidity sensors. Raspberry Pi Its easy to connect these sensors to your Raspberry Pi. For DHT11 and DHT22 sensors, don't forget to connect a 4 - 10K resistor from the data pin to VCC & if 4 doesnt work, try 10K. If your sensor has a white wire, leave it disconnected.
Using the DHT11 Temperature Sensor with the Raspberry Pi
DHT11/22 Sensor Signal to Raspberry Pi PIN 7 (GPIO PIN 4) DHT11 / DHT22 Wiring Diagrams for the Raspberry Pi (Sensor Only) Use the following wiring diagram if you have a DHT11 or DHT22 sensor with and need to add a separate pull up resistor.
interface dht11 dht22 with esp32 and display values on web
Wiring diagram of DHT11 interfacing with ESP32 Wiring diagram of DHT22 interfacing with ESP32. Pinout of both DHT11 and DHT22 sensors are the same as you can see in the picture. The first pin for both sensors is the Vcc pin. You should connect it with the 3t pin of ESP32.
