How DO I Add DHT11 library .. I tried Changing DHT22 to DHT11 in source code But it doesnt work. its comming up with error saying ;

'dht' does not name type

DCT22_test:7: error: 'dht' does not name a type

DCT22_test.ino: In function 'void sendTempToNetwork(EthernetClient)':

DCT22_test:62: error: 'DHT' was not declared in this scope

I am trying to use DHT11 in same code above !

Thank you

Before i dive into that, did the code I sent to you work OK ?

Peter

As for DHT22 vs DHT11 the only change is this

    int chk = DHT.read22(DHT22_PIN); change to     int chk = DHT.read11(DHT22_PIN); assuming the DHT11 is on the same pin as the variable DHT22_PIN is configured for which in the code is pin 2

?Dear Sir,

It did. Just need to add LCD part now. Really impressive I had no qlue thought it won't work . but it did.

Thank you

link in the LCD your using, maybe a link to the product page, there are so many I want to ensure I am helping with the right one
