Below has differing code from the above. Works the same. Arduino with LCD Display and DHT11 Temperature-Humidity Sensor In Depth Look at AC Power Control with Arduino YouTube Video for Arduino AC Power Control Four part series: Experimenting with the PCA9555 32-Bit GPIO Expander with Arduino ...
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...
Open example: Arduino => File => Examples => SimpleDHT => DHT11Default Connect the DHT11 and upload the program to Arduino. Open the Serial Window of Arduino IDE, we got the result as follows. === Sample DHT11... Sample OK:19*C,31H === Sample DHT11... Sample OK:19*C,31H ...
