Example code HC-SR04 with DHT11 temperature sensor and Arduino As mentioned earlier, the speed of sound strongly depends on the air temperature. If you want to measure long distances (3-4 m) it can be a good idea to add a DHT11 orDHT22temperature and humidity sensor to your setup. Thi...
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...
-最终代码,Thingspeak_final_code.ino和DHT11库已附加在此处。 -请注意,代码中ESP8266的波特率是115200。如果ESP8266的波特率不同,请相应地更改代码。 -如果使用波特率为9600的UNO,则用软件串行替换代码中的“ Serial2”,并相应地连接电路。 -不要忘记在代码中编辑通道的APIKey。
