Smarthome-Raspi-DHT11

Get room temperature and humidity with DHT11 via a Raspberry Pi and persist data in Firebase. Pull Data from Firebase and visualize Data by using the Python Dash Framework. When the humidity is above 40% for more than one hour, the app sends a message to my girlfriend and me via Telegram

How to run

  1. Follow the Adafruit Library instructions to get Sensor data.
  2. Run the Dash App: python app.py
  3. Run the Notification Manager: python NotificationManager.py

(The firebase credential file is excluded and the telegram token is revoked)

Technology

  • Raspberry Pi with DHT 11, evaluation with Adafruit Library
  • I used Google Firebase (Cloud Firestore) to store and read the sensor data. They have a good api and reasonable free plans.
  • Dash for Data Visualization
  • Telegram API for notifications (e.g. Open the window)
