So far I have looked at outputting the data from my sensors to Flask, Twitter and Azure. However, a simpler option could be to output the date to a CSV (Comma Seperated Value) file that could be used by various programs later on. I've placed the Python code to capture data from the Pi sensors … Continue reading Saving Sensor Readings To CSV (Python / Raspberry Pi)

Last month I added a Pimoroni breakout garden with a temperature/pressure sensor to my Raspberry Pi, and built a whole project around it. As the breakout garden has 2 additional slots that were empty I have decided to use one for the LTR-559 (sadly to my knowledge not a droid in Star Wars) Light & … Continue reading Lux Twitter Tweet Bot (Python / Raspberry Pi)

With the Python program (see part 1 and part 2) collecting Tweets from Twitter and then analysing the data via Azure to see if the sentiment is positive, neutral or negative it only means I am one step away from being able to retweet positive tweets. I've reused some of the code from my earlier … Continue reading Retweeting Positive Tweets, Or Part 3 Of Analysing Tweet Sentiment with Azure (Python / Raspberry Pi)

With the Pi successfully reading temperature and pressure from the sensor, and connecting successfully to Azure it left one more step in my project - outputting the data in a meaningful way.  For this part of my project I'm looking to collect the data Azure is receiving and put it into a line graph which … Continue reading Azure IoT Hub / Raspberry Pi IoT Project – Connecting Pi, Azure and Power BI.

I have looked at the best Raspberry Pi & sensor for my IoT Temperature Project, setup the hardware, took measurements and outputted them to a Twitter bot. Then yesterday I created an Azure IoT Hub, which means I now need to connect the Raspberry Pi to the Azure IoT Hub. The first step is to … Continue reading Azure IoT Hub / Raspberry Pi IoT Project – Connecting Pi and Azure (Raspberry Pi / Python)

Now that the temperature sensor is taking readings and tweeting them I want to look at exporting the results another way, and what better way than a web page. I have created guides on using a Raspberry Pi as various different types of web server; see: Node.JS Apache / WordPress Django So today I am … Continue reading Installing / Using Flask or Raspberry Pi IoT Project: Temperature Part 4 (Raspberry Pi / Python)

With the Raspberry Pi set up (see parts 1 and 2) it is time to expand the project. First up is bringing back the geektechstuff_automated twitter bot to get it to regularly tweet the room temperature. Thankfully my previous experience with Twitter let me reuse some of my old coding: And using a crontab I … Continue reading Raspberry Pi IoT Project: Temperature Part 3 – Tweet Bot (Raspberry Pi / Python)

In part 1 I looked at the planning of my new Raspberry Pi / IoT project (temperature readings) and decided on the hardware to use. I already had the Raspberry Pi 3 (and appropriate microSD, power etc...) so the only thing missing was the temperature sensors. I ordered the sensor highlighted in part 1 (BMP280 … Continue reading Raspberry Pi IoT Project: Temperature Part 2 – Testing Hardware (Raspberry Pi / Python)
