# DHT Humidity Sensing on Raspberry Pi

This project is a uses the AdaFruit libraries for sensing temperature using DHT11 sensor and a Raspberry Pi.

> [!IMPORTANT]
> Check the [requirements](https://git.kska.io/notkshitij/DHT11/src/branch/main/REQUIREMENTS.md) first.

## Main method

> [!NOTE]
> This is the main method, using AdaFruit library. For an easier method, checkout [## Alternative method](https://git.kska.io/notkshitij/DHT11#alternative-method)

1. Install some prerequisite packages:
```shell
sudo apt update &&\
sudo apt install git -y

```

2. Clone the project:
```shell
git clone https://git.kska.io/notkshitij/DHT11.git
```

> Alternatively, you can also [download the zip file](https://git.kska.io/notkshitij/DHT11/archive/main.zip)

3. Change the current working directory to the folder in which the project was cloned:
```shell
cd ./DHT11
```

4. Run the `setup.sh` script:
```shell
./setup.sh
```

> [!IMPORTANT]
> After running the code, and completing the execution, run `deactivate` in the terminal to exit the virtual environment.

---

## Alternative method

> [!NOTE]
> This alternative method uses the `DHT11` python library for reading the sensor data.
> This is a pure Python library for reading DHT11 sensor on Raspberry Pi.

1. Install prerequisites:
```shell
sudo apt update &&\
sudo apt upgrade -y &&\
sudo apt install python3 python3-pip -y

```

2. Setup a virtual environment & install the library:
```shell
mkdir /home/$(whoami)/temp-sensor
cd /home/$(whoami)/temp-sensor
python3 -m venv .
source bin/activate
pip install dht11 setuptools RPi.GPIO

```

3. **Download** and **run** the code [alt-temp.py](https://git.kska.io/notkshitij/DHT11/src/branch/main/alt-temp.py)

> [!IMPORTANT]
> After running the code, and completing the execution, run `deactivate` in the terminal to exit the virtual environment.
