# SimpleDHT
|
||
|
|
|
||
|
|
Simple, Stable and Fast Arduino Temp & Humidity Sensors for
|
||
|
|
[DHT11 etc](http://learn.adafruit.com/dht).
|
||
|
|
|
||
|
|
1. Simple: Simple C++ code with lots of comments.
|
||
|
|
1. Stable: Strictly follow the standard DHT protocol.
|
||
|
|
1. Fast: Support 0.5HZ or 1HZ sampling rate.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
To use this library:
|
||
|
|
|
||
|
|
1. Download the zip from specified version: https://github.com/winlinvip/SimpleDHT/releases
|
||
|
|
2. Import to Arduino: Arduino => Sketch => Include Library => Add .ZIP Library...
|
||
|
|
3. Open example: Arduino => File => Examples => Simple DHT sensor library => DHT11Default
|
||
|
|
4. Connect the DHT11 and Upload program to Arduino.
|
||
|
|
5. Open the Serial Window of Arduino IDE, we got the result as following.
|
||
|
|
|
||
|

```
|
||
|
|
|
||
|
|
> Remark: For DHT11, no more than 1 Hz sampling rate (once every second).
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
This library including the following examples:
|
||
|
|
|
||
|
|
1. DHT11Default: To sample the temperature and humidity.
|
||
|
|
1. DHT11WithRawBits: To sample the temperature and humidity, output the 40 raw bits.
