GPS is rapidly evolving from just being useful to being essential in our current world. Fortunately, there is an easy-to-configure, low-powered, Arduino-supported chip called UBLOX…

We’ve already tackled the schematic diagram of the famed Arduino UNO. It is now time to assemble it in your own breadboard! Here are the…

Circuit design always starts with a question of how to make things work. Engineers grab the nearest development boards, more often than not an Arduino,…

I still can’t believe how much this board costs considering its features. If you’re tired of messy wires and would like to put on some…

I really love the tutorial written by JP how to use ESP32 Deep Sleep. For the beginners who are not familiar with ESP-IDF and prefer…

Get deeper into the Arduino craft by looking into a reference design. In here I will get into details with the basic arduino schematic diagram…

Part #2 – The LoRa gateway In my other post I made an introduction to Long Range (LoRa) communication. Now let us put this into…

Part #1 – The sensor nodes In my other post I made an introduction to Long Range (LoRa) communication. Now let us put this into…

Usually we use WiFi, Bluetooth or GSM to connect our sensor devices with the world of IoT. But what if neither of that is available (or not affordable like GSM)?

Use an ESP32 to monitor temperature, humidity and eCO2 – then toss the data online!
