DH11 Temperature and Humidity Sensor With Arduino

This is a Tutorial On how to use the DH11 Temperature and Humidity Sensor with Arduino.

This video Shows the full Procedure on how to use this Sensor.

1) Click here To download the DH11 Library for Arduino.

2) Extract the Zip File.

3) Paste the Extracted Folder to C: \Program Files \ arduino \ Libraries.

4) Open the Arduino IDE and Click "OPEN".You will find that a new option has been added (dht11_read).

5) Open this Sketch and Upload this to your Arduino.

6) Thats it, You are good to go!!!!.

1) According to the sketch, Connect the Second Pin of the Sensor to the DIGITAL PIN 4 of the Arduino.Otherwise it will show an error.

2) it is not necessary to connect a 10K Ohm Resistor in between the VCC and Signal (1st and 2nd) Pin of the Sensor.
