Domoticz part 8 – Stable instance of Domoticz, 24/7/365 mode – high availability at home

Since the inception the Domoticz project tried to fulfill many goals: availability of many plugins and supporting lots of different hardware user ideas that helped building automation processes scripts (LUA, Python) and if, then, else hacks integration of third-party solutions open-source libraries support for different platforms – and SBC, that play own role with their limits and properties As a result, a both fresh and advanced user finds himself in a situation where the system – ceases to work at all, or requires frequent restarts,…

CCS811 & BME680 with Raspberry Pi 0 W

Preview: Measuring air quality using Bosch BME680 and CCS811 – IAQ, TVOC

It’s not only the SMOG that we can measure, let’s find out if our indoor air is of good quality. Soon to be published: test of two sensors Bosch BME680 by Nettigo – IAQ sensor along with temperature, humidity and pressure CCS811 – Carbon Dioxide (CO2), TVOC stay tuned…

ESP8266 and SMOG part three: sensor protection, cloud upload

Język/Language: Polski English Last time we updated our simple SMOG sensor with display (OLED) and added BME 280 to verify the SMOG measurements – the environmental sensor – as we know that humidity over 70% can add up to the SMOG. It’s time now to protect our sensor. Why do we need sensor protection? Smog sensor – it’s laser in particular – has a limited lifetime – datasheet states 8000 hours. Both the fan and the laser diode should not work continuously – because of wear…

ESP8266 and SMOG part two: OLED display, measuring conditions

Język/Language: Polski English Last time we build a simple SMOG sensor, it’s time to add display (OLED) and to verify the SMOG measurements – the environmental sensor – as we know that humidity over 70% can add up to the SMOG. What will you need? Hardware working SMOG sensor from previous entry, the Nettigo store has currently promotion – use the code: DIY_SMOG_15 to get 15% off the price BME280 board – temperature, humidity and pressure – the BME280 and please mind that the board supports VCC of 5V OLED…

ESP8266 and SMOG: Quick and snappy SMOG sernsor with WiFi interface – first, basic version

Recently, we built a smog sensor which measures PM2.5 and PM10 ppm particles common in SMOG. This time let’s focus on something easy to do, without deliberations on extending life of the sensor. The Nova Fitness SDS011 (also versions 018 or 015) has proven to be quite accurate, with a good life expectancy, even with nearly theoretical unsupported air humidity above 70%. Today I will try to show you the mobile version of the sensor, using the cheapest elements, and then expand it with a…

Domoticz part. 7: Heating your house with Z-Wave

We do know how to install domoticz. But how easy is to control heating in your house/flat? After full season of testing radiator control – I can recommend a very interesting and useful heating control system that you can setup in your home or apartment. All just by means of adding radiator thermostats with Z-Wave radio. What will you need? Software Up to date Domoticz installed on PC, Raspberry Pi, Orange Pi or other – with Linux operating system Hardware One free USB 2.0 or…

PLNOG 18 i 19

PLNOG is a conference held in Warsaw and Krakow twice a year. This is the place where IT and telco people meet. Last time I spoke about some of my experiences in building small devices, listen if want to (Polish only): During next PLNOG 19 I’m going to talk about SMOG sensor: Big Thank You to all who were present – hope you liked it!

Power supply for Raspberry Pi, Orange Pi, ESP8266 – XBOX 360 PSU modification

Proper supply of power is a very important part of our SBC (Small Board Computers) projects. Power supplies with too low current efficiency, instability and lack of filtration – often lead to accidental resets, lack of sensor readings or simply unstable behavior of SBCs. One of the solution is to modify the power supply from Microsoft console – XBOX 360. WARNING: We will work with high currents and high voltage, which requires basic knowledge of electrical engineering. The author is not responsible for accidents and…

Tracking gliders, airplanes, helicopters and baloons, part 3 – FLARM

We already know how to track airplanes using DVB-T USB dongle and Orange Pi or Raspberry Pi. Let’s move on to a new system that allows tracking of light aircrafts: gliders helicopters baloons smaller airplanes FLARM – is a collision avoidance system for light aircrafts, popularized and approved by EASA, gaining traction, used mainly on gliders in Poland and Europe. We’re not going to use it to avoid collision – but to receive position and track light aircrafts – so we can share them on the…

SMOG = Raspberry Pi B z SDS011

[UPDATED 07-11-2017] SMOG sensor – 2,5 and 10 micro meter particles

[Last changes: Additional data from richer stations, Open-Smog Integration] SMOG is common nowadays in big cities. Let’s put together a working, precise own SMOG sensor, first for the 2,5 and 10 μm size particles. There is one issue – the choices are many, but only few are reliable, precise and have affordable price. Finally – after a log searching, I’ve chosen Nova Fitness SDS011: precision is OK fan included ability to mount a small tube to access external air very realiable UART with USB converter included…
