Raspberry Pi Mini Weather Station

Raspberry Pi Weather Station

Measures:

• Temperature
• Humidity
• Atmospheric Pressure
• Lux

Check out the dashboard!

Parts you'll need:

• AM2302 Temperature / Humidity Sensor
• BMP180 Temperature / Barometric Pressure Sensor
• DS18B20 Waterproof Temperature Sensor
• TSL2561 Digital Lumosity Sensor

Installation Instructions:

These instructions have been tested with the latest version of Raspian, however they should run in most distributions of Linux fairly easily.

Wire up the sensors as shown here:

Set up the AM302

Here we set up the AM2302 Humidity Sensor.

Clone the Adafruit Python DHT Library

git clone https://github.com/adafruit/Adafruit_Python_DHT.git

Build some tools

sudo apt-get update

sudo apt-get install build-essential python-dev python-openssl

sudo python setup.py install

Set up the DSB18B20

You will need to add One Wire Support:

sudo nano /boot/config.txt

Add the following line:

dtoverlay=w1-gpio

Reboot the Pi:

sudo reboot

Add smbus and i2c tools:

sudo apt-get install python-smbus
sudo apt-get install i2c-tools

You may get "already installed" Messages from this

sudo nano /etc/modules

Add the following:

i2c-bcm2708 
i2c-dev

Modify boot config:

sudo nano /boot/config.txt

Add the following lines:

dtparam=i2c1=on
dtparam=i2c_arm=on

Reboot the Pi:

sudo reboot

Set up the TSL2561

cd ~/sources

wget https://raw.githubusercontent.com/adafruit/Adafruit-Raspberry-Pi-Python-Code/master/Adafruit_I2C/Adafruit_I2C.py
wget https://raw.githubusercontent.com/seanbechhofer/raspberrypi/master/python/TSL2561.py

(Thanks to Sean!)

Set up the BMP 180

git clone https://github.com/adafruit/Adafruit_Python_BMP.git
cd Adafruit_Python_BMP
sudo python setup.py install

Test the sensors

git clone https://github.com/JeremyMorgan/Raspberry_Pi_Weather_Station.git reader
cd reader
sudo python readings.py dryrun
