==Introduction==
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. <br>
It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and provides a pre-calibrated digital signal output. <br>
This DHT11 sensor has fast response, anti-interference ability, excellent reliability and long term stability.<br>

<span style=color:red> '''Special Note:''' <br>
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface. <br> If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module. </span><br>
<br>

<span style="color: red">'''Little Knowledge:'''</span> <br>
* If the data is scrolling very fast, you can’t make out the data clearly, so you can modify the Delay time in the code to check it easily.
