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 specifics on setting it up o...
Before you can use the DHT11 on the Arduino, you’ll need to install theDHTLib library. It has all the functions needed to get the humidity and temperature readings from the sensor. It’s easy to install, just download the DHTLib.zip file below and open up the Arduino IDE. Then go ...
dropdown menu is to filter out the topic of the library, like communication, device control, display, sensors, etc. In the search bar, you can type a search term such as a name, and you’ll get filtered results. In this example, we will be using a DHT11 sensor Arduino Library. ...
The code start by including the library for the DHT11 sensor and theLowPowerlibrary. For downloading theLow Power libraryfollow the link. Then we have defined the Arduino pin number to which the data pin of the DHT11 is connected and created a DHT object. #include <dht.h>#...

I have included 5 examples with a wiring diagram and code so you can start experimenting with your sensor. We will first look at an example that does not use an Arduino library. Next, I will show you how you can use theNewPinglibrary to create a more compact code. ...
You can download the code by clickinghere. Step 5: Code The code for the DHT11 sensor is well commented and self-explanatory but here is some explanation of the code. At the start, the library to use DHT11 is included, variables are initialized and pins are also initialized. ...
Arduino has a detailed walkthrough ofhow to install librariesfor its IDE. And Adafruit hasdetails on the MQTT API. The reed switch does not require a library of its own because you will read whether voltage is present (“HIGH” or a value of 1) or not (“LOW” or a value of 0) ...
The DHT11 MicroPython Code for Raspberry Pi Pico comprises of so many dependencies. We have to write MicroPython code for the DHT11 Library and also for the OLED Display. The code comprises of 3 parts: 1. SSD1306.py 2. dht.py
