DHT22 Sensor Pinout, Specs, Equivalents, Circuit & Datasheet
Where DHT22 Sensor is Used. The DHT22 is a commonly used Temperature and humidity sensor. The sensor comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data. The sensor is also factory calibrated and hence easy to interface with other microcontrollers.

DHT22 Temperature-Humidity Sensor - Waveshare Wiki
This is a calibrated digital temperature and humidity module with onboard sensor DHT22 (AM2302), which features higher accuracy and a wider measuring range than DHT11. It can be used for detecting ambient temperature and humidity, through the standard single-wire interface.
DHT22 temperature-humidity sensor + extras : ID 385 : Adafruit ...
The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to …

2019年7月26日 · It can be difficult to pick the best temperature sensor for your Arduino, ESP32 or ESP8266 project. Compare these sensors: DHT11, DHT22, LM35, DS18B20, BME280 and BMP180 to find the most suitable.
Arduino DHT22 Library Code Examples & Tutorial - DeepBlue
In this tutorial, you’ll learn how to interface Arduino with DHT22 Sensor (Humidity & Temperature Sensor) and use it for monitoring humidity and temperature applications. We’ll discuss how to install and use the Arduino DHT22 Library and its functions.
Learn How to Use the DHT22 with an Arduino; Full code …
The DHT22/11 sensors use a serial communication interface, operating over long distances (over 20m is claimed DHT11, 100m for DHT22). You can buy sensors without a breakout board but the board is convenient and has a 10k pull-up resistor that is on-board. In fact the pull up resistor should be from 5k to 1k then the distance can be further.
