Maintainer: beegee_tokyo. Read the documentation. Go to repository. Compatibility. This library is compatible with the esp8266, esp32, samd, avr … The DHT11 and DHT22 sensors are used to measure temperature and relative humidity. These are very popular among makers and electronics hobbyists. These sensors contain a chip that does analog to digital conversion and spit out a digital signal with the temperature and humidity. This makes them very … See more DHT sensors have four pins as shown in the following figure. However, if you get your DHT sensor in a breakout board, it comes with only three pins and with an internal pull-up … See more To follow this tutorial you need to wire the DHT11 or DHT22 temperature sensor to the ESP32. You need to use a 10k Ohm pull-up resistor. Here’s a list of parts you need to build the … See more To read from the DHT sensor, we’ll use the DHT library from Adafruit. To use this library you also need to install the Adafruit Unified Sensor … See more Wire the DHT22 or DHT11 sensor to the ESP32 development board as shown in the following schematic diagram. In this example, we’re connecting the DHT data pin to GPIO 4. … See more WebConnect the DHT11/DHT22 to ESP32/ESP8266 along with a 10K ohm pull-up resistor. The connection diagrams are shown in the pictures below. ... Importing DHT Library.
