Now let’s look at the code for interfacing the DHT22 sensor. For that first install the Adafruit’s DHT sensor library and Adafruit Unified Sensor Driver through the library manager. Then create a blank sketch and paste the code at the end of this article into it. #include <Wire.h> #...
如果不出错的话就能安装好了。 (2)dht22的代码如下,(如果是dht11,把sensor = Adafruit_DHT.DHT22改为sensor = Adafruit_DHT.DHT11) 在Adafruit_Python_DHT目录外新建一个.py文件 #!/usr/bin/python import Adafruit_DHT sensor = Adafruit_DHT.DHT22 pin = 4 #GPIO4 humidity, temperature = Adafruit_DHT...

Code: void DHT_Start(void) { // Here we send the 'start' sequence to the DHT sensor! We pull the DHT_IO pin low for 25mS, and // then high for 30mS. The DHT sensor then responds by pulling the DHT_IO pin low, and then pulling it ...
Caution: DHT22 digital temperature and humidity sensor is designed for analog sensor interfaces.The analog port will be used as the digital which will not occupy the original digital port of the Arduino.The lines of the sensor which can transform the analog function to digital that can be use...
