# MicroPython DHT11溫濕度感測器

在嵌入式系統中常見的溫濕度感測器DHT11，在micro:bit中也可以使用MicroPython來完成量測的程式。這次我們使用是以下的這個模組：

同樣地，請下載之後解壓縮，然後把dht11.py上傳到micro:bit板子上，利用以下的程式即可讓micro:bit的LED顯示器以捲動的方式顯示出目前正確的環境溫濕度：

```python
from microbit import *
from dht11 import DHT11

while True:
    sensor = DHT11(pin0)
    t, h = sensor.read()
    display.scroll("{}C,{}%".format(t, h))
    sleep(2000)
```
