For those who follow my blog know that I have a 3D printer. Besides thinking up and creating everyday solutions with my 3D printer, I also like to draw 3D models. In this case the Plantower PMSA003i Digital Laser Dust Sensor. By drawing 3D models I learn “playfully” more and more. I sometimes made models in the past, …
Since the corona virus I have become increasingly aware of my environment. I also started to delve deeper into my living environment and in particular the air quality. I Already wrote a blog about the NASA Clean Air Study, this blog explains how you can clean your indoor air with plants. But I don’t know how …
He’s making a list, He’s checking it twice, He’s gonna find out who’s naughty or nice, Santa Claus is coming to town …. Now that the days are starting to get longer again, the holidays are slowly coming our way. This Christmas, I hope my super sweet Santa surprised me with a perfect gift. To …
Know the status of something you can open or close. Simple and easy to install with no tools required, The ESP8266 – HomeKit Window Contact Sensor combines simple technology with everyday peace of mind. And even better, it can control other HomeKit accessories in your home when doors or windows are opened or closed. ESP8266 …
Have you ever wanted to create a project that involved non-contact detection, such as detecting the closing of a door, counting the number of revolutions of a wheel, or creating a speedometer? Then this blog about the Hall effect sensor is for you. This project uses a Hall effect sensor to detect the presence of …
In my previous blog here I tested the ESP HomeKit Software Development Kit. I am so enthusiastic about this Software Development Kit, that I going to write a few blogs about this genius software. In each Blog I will address a other accessory that you can add to your HomeKit without the need of a …
Say if you have a sensor that is supplying a voltage that is much higher than you may need for a particular part of a circuit, such as for a chip in the circuit in this case a ESP8266. The sensor is run off of a 5.0V supply but the chip (ESP8266) in the circuit …
As you know I made some PDB’s in the past for some projects. From “Normal” components I switched over to SMD. But now I want to make things as small as possible. So I was thinking about a project I did a time ago, with a Raspberry Pi Zero W. This raspberry has so called …

MQ135 sensor is a SNO2 with a lower conductivity of clean air. The MQ series of gas sensors uses a small heater inside with an electrochemical sensor. These sensors are sensitive to a range of gases used at room temperature. When the target explosive gas exists, the conductivity of the sensor increases more and the …
