WSPR first data analysis

My WSPR data collector is now running some days and I started with some basic data analysis.

The power on the bands 60m to 20m is about 100mW!

Inspired from some work found on the Internet and the full functionality of my U3S I've build an automatic spot collector. The spot collector pulls every 5 minutes my spots from WSPRnet.org and puts it into a MYSQL database for later analysis. See the schematic for this setup

IoT Powersensor #2

For the main power distribution in my house, I also build a powersensor. The basic idea is the same as for this sensor. But the electric meter is already build into the distribution cabinet, so this power meter uses the so-called S0 bus of the power meter inside the cabinet.

IoT Powersensor #1

This is my first power/voltage sensor I've build. It is based on an commercially available powermeter from B+G E-Tech. You can find them on eBay or their website. It provides a 90ms pulse for each Wh flown through it.

The line voltage is measured using a simple transformer and a circuit based on the schematic from OpenEnergyMonitor. The software to measure the line voltage is also from OpenEnergyMonitor embedded into my sensor framework.
