This is done by entering the following command:

Next thing we need to do is install the DHT python library. RELATED: DHT11 Sensor Wiki Page Python Code for Raspberry Pi DHT11/DHT22

( NOTE: Some cost reduced modules do not include this LED.) If you wired everything up correctly, you’ll see a red LED glowing on the DHT11 module.

10K Ohm Resistor between DHT11/22 PIN 1 and PIN 2.

Use the following wiring diagram if you have a DHT11 or DHT22 sensor with and need to add a separate pull up resistor.

Use the following wiring diagram if you have a DHT11 or DHT22 module with an integtated pull up resistor. There’s a link to these in the description.ĭHT11 / DHT22 Wiring Diagrams for the Raspberry Pi (Module) It makes the Pi’s pinout much easier to follow. You don’t need a breadboard for this project, but I feel like it makes things much simpler to understand, especially if you use of these breakout cables. RELATED: Installing Raspbian for the First Time Using a Breadboard and Breakout Cable Wiring the DHT11 or DHT22 to the Raspberry Piīefore we can begin using the DHT11 Temperature Sensor with the Raspberry Pi, we have to wire it to the Pi. Here’s a quick parts list for this project to get you started: If you decide to use the standalone sensor, we have a wiring diagram for that below as well. The difference is that the module includes the 10K Ohm pull up resistor on the board.

I should also note that these sensors come as separate components or as modules. These sensor are ideal for remote mounting due to the fact that they can operate up to 65 feet (20 meters) apart using a long wire. If you have a DHT22, just follow along and everything will work the same and you’ll get more accurate readings! You will need to change the code snippet to reflect your sensor though. In this project we’ll be using the DHT11. However, the DHT22 is a more accurate sensor. The DHT11 and DHT22 are fundamentally the same from a wiring and software perspective. Especially to keep tabs on how hot your Raspberry Pi is, if its in a non-ventilated box in the summer heat. Using the DHT11 temperature sensor with the Raspberry Pi is a great way to get temperature and humidity readings in your projects. Genie Pi version 1.In this tutorial, we’re going to cover using the the DHT11 (or DHT22) temperature and humidity sensor with the Raspberry Pi. This library is also required for the Raspberry Pi demo programs.
