If you’re trying to read the temperature and humidity from the DHT11, DHT22, AM2302 or AM2301 sensor and you get an error message in your Serial Monitor, follow the next steps to see if you can make your sensor work. Learn how to fix the Failed to read from DHT sensor error. If...

Re: DHT22 and "Failed to read" messages Postbytjstroker»Thu Jul 09, 2015 11:41 am This sensor is obviously bad. See the humidity readings are also cut significantly. DHTDHTxx test! Humidity: 42.90 % Temperature: 23.30 *C 73.94 *F Heat index: 25.16 *C 77.29 *F ...
Hi @elle2 I'm seeing the same issue with a dht11. It works fine when I don't define a HomieNode, but the moment I do, it hangs while trying to read and then crashes after a few seconds. After reading your issue, I watched the logs for my mqtt broker and can see that the cra...
The Raspberry Pi Pico comes with a built-in temperature sensor connected to ADC4. Learn how to get temperature data from that sensor using Arduino IDE in Celsius and Fahrenheit degrees.

若myeclipse报 “Exception in thread "main" java.lang.OutOfMemoryError: Java heap space ”错误,我们可以通过一下方法进行处理:首先, 打开Eclipse软件,选择菜单栏run,在二级菜单中选择 Debug Configurations,然后:在弹出的窗口中选择(x)=arguments选项卡,VM arguments中输入所需要的内存最大占用量,比如输入-Xmx...
Thank you very much to share this nice code ! I have a problem. I try to use this code with a DHT22. On the charts it Always shows the same value for temperature (24.3°C), humidity (57%). If I print the values in the serial monitor Inside the loop, the values changed and are...
The code is written in such a way that any basic sensor’s input can be stored (like DHT11 sensor or LDR). The code doesn’t change much from the previous one where we write, read and delete through Serial monitor. The code will take input from the sensor ...
