Free Elektor Article: Power Outage Detector with Text Messaging
https://www.electronics-lab.com/free-elektor-article-power-outage-detector-text-messaging/
Power outages are fairly rare in central Europe, and when they do occur, they are usually short. However, if the heating system of your holiday home doesn’t start up again after a power outage, the consequences can be costly. And even if only your freezer at home stops working while you’re on holiday, the stench […]

ESP32 LoRa Sensor Monitoring with Web Server (Long Range Communication)
https://www.electronics-lab.com/project/esp32-lora-sensor-monitoring-web-server-long-range-communication/
I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32. The LoRa communication capacity of the board […]

ESP8266 based Online Weather Widget using Wemos D1
https://www.electronics-lab.com/project/esp8266-based-online-weather-widget/
A few years back I wrote this tutorial on connected weather monitor with plans of creating a 3D printed enclosure to make it portable and easy to use. I never got around doing that but a few days ago, I came across a similar project built by BitsandBlobs, which went as far as creating the […]
Harmonics
https://www.electronics-lab.com/article/harmonics/
Introduction Periodic signals are not always perfect sinusoidal patterns such as presented in one of our previous tutorials about Sinusoidal Waveforms. Sometimes, signals can indeed be a superposition of simple sine waves and they are known as complex waveforms. In this tutorial, we will focus on complex periodic waveforms to understand what they consist of […]
