My home environment and air quality monitoring system

We often hide the electronics in a box. And cases can be done well and nicely. But when our main interest is electronics then it is sad to hide it. That is way like to do it the opposite way. Sensors will measure particulate matter (Ultrafine dust PM2.5 and fine dust PM10), co2, TVOC, ambient […]

Dust sensor

Nova PM sensor SDS011 can measure fine dust and smoke = particulate matter (MP) concentrations in two categories: Ultrafine dust particles with a diameter of 0 – 2.5 micrometres (μm/m3). Output PM2.5 Fine dust particles with a diameter 2.5 – 10 micrometres (μm/m3). Output PM10 The sensor is designed with a built-in fan to ensure […]

Serial Plotter code

This is my standalone serial plotter. I like to use Arduino, Esp866 etc. and then i started to learn python and decided to make something useful. Something that i will use and what is missing now for me. Although Arduino Ide contains serial plotter. It is little bit different. Written in python 3 and Qt5. […]

Serial Plotter

My first try to make useful GUI application a Arduino Serial Plotter Simple serial plotter for Arduino and other devices to quickly visualize generated data. GUI is made in Python3 + Qt5 . Much work remains to be done. But this is a good start. https://github.com/taunoe/tauno-serial-plotter

Ambient light sensor TEMT600

TEMT6000 is ambient light sensor. It is sensitive to visible light much like human eye and has peak sensitivity at 570nm. Visible spectrum is 390 – 700 nm. The sensor can handle voltages from 3.3v and 5v. The sensor has been designed into a voltage divider circuit. To read that voltage connect SIG pin to […]

Electronic “paper crane” or orizuru – freeform circuit

I had a bunch of smd LEDs and no idea what to do with them. But then, when I had watched all these events in Hong Kong. And when I had seen how they make this paper cranes I decided to make my own version. It use ATtiny13 AVR microcontroller and software PWM to slowly […]
