温湿度传感器DHT11的STM32驱动实现 1.DHT11简介 DHT11是一款性价比极高的温湿度传感器,其温度测量范围:0-50℃,测量误差:±2℃;湿度测量范围:20-90%RH,测量误差:±5%RH。尽管其精度不高,但是可以满足大部分应用场合。为了通过DHT11读取温湿度,我们更关心的是其与单片机的通信问题,DHT11共有三个引脚,其中VCC...
You may also want to try powering the DHT sensor from 5V (we found sometimes it really needs more power) but still having the 10K pull-up resistor to 3.3V volts) Now create an instance of either theDHT11orDHT22class, depending on the type of sensor you're using (for the AM2302 sens...
I also added initial support for Arduino Due. Adafruit Industries published this originally under MIT license. To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder DHT. Check that the DHT folder contains DHT.cpp and DHT.h. Place the DHT library ...
