Long time, no see! Some years ago, I started a project to develop some low power environmental sensors. But for different reasons, the project was on hold obviously. There were a few working prototypes but Read More …
I designed the circuit with the idea to use batteries without a voltage regulator, because they use current every time. The sensor board should stay in low power mode most of the time, so a Read More …
This is the first and unexpectedly working (!) prototype: It has a dimension of 80 mm x 80 mm. The strange shape is because a had a case in mind. Therefore, I had to align Read More …
I made my first IOT experiences with the ESP8266 with the ESP-Easy firmware. Therefore, I wanted to keep the hardware compatible. For performance reasons, I later switched to my own code (which I will publish in the Read More …
This series about my home automation sensor nodes can also be seen on hackaday.io: https://hackaday.io/project/20588-espmobe-battery-powered-esp8266-iot-sensor I like home automation a lot. For automation purposes data must be collected. I also like open software. But mostly Read More …
