Summary of Sending weather data via Twitter using Rasbperry Pi and DHT22
This project connects a DHT22 sensor to a Raspberry Pi to monitor temperature and humidity. Data is shared via Twitter requests and stored online for web access. The setup involves hardware connection, installing the Adafruit DHT Python library, and adapting previous C programs to new Python scripts for data publishing.
Parts used in the Raspberry Pi Weather Monitor:
- Raspberry Pi
- DHT22 temperature and humidity sensor
- Adafruit DHT Python library
UPDATE: adding a light sensor to the device.
The idea behind this project is connect some sensors to the Raspberry Pi and put the information available on demand via Twitter requests and put sensor history data online on the web
To do that, I used a DHT22 temperature and humidity sensor connected to the Rasberry Pi.
You can get all the detailed steps from Adafruit website
When you have setup all the hardware, you must get into software stuff, to do that you must download the Adafruit DHT Python library (instructions here)
To publish the weather data on the web you must follow my old DHT11 post and this one, but you must change the original DHT11 C program to the new DHT11/22 python script:
