比如配上断路器,可以做成智能家居,当达到多少温度的时候打开空调,多少湿度的时候打开加湿器等等。据说DHT11是相对来说比较廉价的温湿度模块。这点我在之后的应用中也感觉到了-_-///,后面我再提。 DHT11模块一般淘宝上买的有两种,一种就是我下图这样的,一个蓝色小盒子带上一个电路板,有三个针脚,配上一个电源...

Raspberry Pi 16X2 LCD Display We have another tutorial on the DHT11 for theArduinothat goes into detail on relative humidity and how the DHT11 measures it. So instead of repeating all of that here, check outHow to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the...
We also run a simple experiment in which we measured the temperature in the same environment using all temperature sensors over time. With this experiment we could see how the sensors react to temperature changes. We’ve ran this experiment for approximately 36 hours and we’ll show you the ...
If you have any questions about how to set up the DHT11 humidity and temperature sensor on your Arduino, just leave a comment below and I will try to answer it… And if you like our tutorials, please subscribe! Also, feel free to share this if you know anyone else that might find it...
