How to Create a personal weather station using RPI Sense hat

Posted on by

Would you like to have the RPI tell you more about your house?
Need to know about barometric pressure or humidity?
Stay tuned and I will show you how to use your RPI and the Sense hat to get this information

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install python3-flask
sudo apt-get install sense-hat
nano weather.py
from flask import Flask, render_template
from sense_hat import SenseHat

app = Flask(__name__)
@app.route(‘/’)
def index():
sense = SenseHat()
celcius = round(sense.get_temperature(), 1)
fahrenheit = round(1.8 * celcius + 32, 1)
return render_template(‘weather.html’, celcius=celcius, fahrenheit=fahrenheit)
if __name__ == ‘__main__’:
app.run(debug=True, host=’0.0.0.0′)
Ctrl x to save file
mkdir templates
nano templates/weather.html

Fahrenheit: {{ fahrenheit }}



! Start web server
python3 weather.py
! Goto ip address of RPI:5000
! You should see a page showing temp in C and F

!! Add humidity and barometric pressure
nano weather.py
Below the line fahrenheit = round(1.8 * celcius + 32, 1), add the following lines:
humidity = round(sense.get_humidity(), 1)
pressure = round(sense.get_pressure(), 1)
Change return line to look like this –
return render_template(‘weather.html’, celcius=celcius, fahrenheit=fahrenheit, humidity=humidity, pressure=pressure)
Modify the html template to look like this
nano templates/weather.html

! Install screen command to allow you to detatch and still be running
sudo apt-get install screen

! Start a screen session that you can disconnect from
screen bash

! Reconnect to screen when you reconnect to rpi
screen -r
