Outdoor solar powered weather station – part 4

Draining and charging One of the critical points I want to test before deploying the station outside is how it behaves if it runs out of power. Think of dark December days with snow on the solar panel. So, I implemented a “drain the battery” routine, which turns on the LED to full brightness and […]

Building an Anemometer – Part 2

In this part I write about the microcontroller I am using and the code. Recently the Raspberry Pi Foundation released a completely new designed microcontroller which can be programmed with MicroPython. Named the RP2040, it is somewhat limited as it does not have Wifi or any other means of wireless communication on board, but it […]

Building an Anemometer – Part 1

This is my most complex 3D printed project so far. The idea: I have now quite a number of weather sensors. I measure temperature with solar-powered sensors which transmit their data using LoRaWan at two locations now. I measure if it rains (qualitative measurement only). But I do not measure wind yet. So to keep […]

Working from home – 12 months in

It was in March 2020 when Corona got serious and all employees where I work were ordered to work from home when ever possible. I was just coming back from a vacation (vacation, travelling, …, remember?) and had to adjust quickly to the new situation. Even when the situation was a bit better during the […]

Environmental Sensors: Remote

Last week my garden sensors gave up – the wooden birds house I used to contain them was simply rotten so I needed a new one. For outside housing of sensors these cheap wooden birds houses are great – no plastic but wood, cheap, and easy to work with. The local home supply store only […]

Environmental Sensors: Lightning

You perhaps know that one of my hobbies is playing around with microcontrollers and sensors. For quite a while now I have deployed ESP8266 based sensor nodes inside and outside of my house. Currently they mainly gather temperature, moisture levels, air pressure and light levels, using BME280 and similar sensors. A while ago I discovered […]
