RaspberryPi with DHT22 Sensor for Humidity and Temperature Data with InfluxDB

I have been playing with RaspberryPI for a while. There are several project I tried to do with RaspberryPI. These boards play a significant role in my home lab for different experiments like Docker Private Repository, Media Server, Ad Blocker with pi-hole, Secure Proxy for anonymity, secure network access with VPN, Home Security Camera/Surveillance, Data Collector or scraper etc. But This time, I did buy a “DHT-22” sensor for monitoring room temperature and humidity. Humidity is my main concern and wanted to see how it fluctuates.

So, my main plan was to get a DHT-22 to connect properly

Count Characters in a Google Sheet

I was trying explore some data in Google Sheet and stumble upon a unique problem. There were several columns and rows of data containing strings. I wanted to count specific string.

I wanted to find out how many “aD” in whole set.

Ansible to change user password

One of the most basic things to do in a Linux Server. We can use just passwd <user> to change the password of a user. But to do that in 100s of server can be a tricky one. Ansible is the savior on that perspective.

Finding an Efficient Solution on Reading and Comparing CSV files

I have always worked with Linux Systems and thus Bash was my go to tool for some specific tasks. But now I am much more aware with Python than Bash as it does give me better grasp on things. I am not saying that for server scripting, Bash can not do some tasks. It can be used in a vast area of things to solve. But I am now comfortable with Python more.

Recently, I did stumble upon of a task that was related to comparing two huge CSV files.

Explore InfluxDB: Part 1

I have been trying to manage time to explore InfluxDB for observability. This article is one of many about InfluxDB and Telegraf. I will cover basic installation here.
