Topic: [LIB] Interrupt driven DHT11 Lib (idDHT11) (Read 52643 times) previous topic - next topic


I've added an example that use 2 sensor, please try it at

One problem with your example is that it doesn't check if the B sensor end acquiring. so maybe sometimes you could get error values.

The part that you said is for debugging, is only to know which error was causing a problem. you can erase it, but you should do something like this to be sure you receive a good measure

Code: [Select]

while (DHT11A.acquiring()) // check if first sensor has ended acquiring
int result = DHT11A.getStatus();
if(result != IDDHTLIB_OK)
} else {
   // DO WHATEVER YOU WANT with the data of the sensor

I'm trying to use idDHTLib with a DHT22 on a Pro 5V, using port 3 on the Pro (and therefore interrupt number 1).
But I cannot read any value, everytime I've got a CheckSum error.

Any idea of what I'm doing wrong ?


edit : ok my very bad, I do not noticed I had to change the callback method. Sorry !
