DHTNEW has some new features compared to the DHTlib code.The constructor has a pin number, so the one sensor - one object paradigm is chosen. So you can now make a DHTNEW object bathroom(4), kitchen(3), etc. The read() function now reads both DHT11 and DHT22 sensors and selects...
这就是Arduino部分的全部内容。下面你可以看到我用DHT11传感器和LED为这个特殊情况编写的确切代码。 #include "ArduinoJson.h" #include "dht.h" dht DHT; //give name to your DHT sensor #define DHT11_PIN A0 //Pin for DHT11 data #define LED_PIN A1 //PIN for LED ...
SimpleDHT sensor library is compatible with multiple low-cost temperatures and humidity sensors like DHT11 and DHT22. A few examples are implemented just to demonstrate how to modify the code for different sensors. MIT License DHT sensor library is open-source and uses one of the most permissive...
The DHT11 sensor senses the surrounding room temperature and gives the result in degrees Celsius. Both the reference and the measured values are displayed on the Liquid Crystal Display (LCD). The Arduino microcontroller, being the processing unit of the system, gets the sensor's measured value ...
