I found a very interesting air quality sensor board from the Germany company OhmTech on Tindy. One of this magic Bosch Sensortec sensor - the BME680 - is used in conjunction with an STM032F72 microcontroller to give a neat "USB-sensor-stick":

Here are some impressions on contest I've participated over the last years ...

As a logical follow on I opted for a separate Diplexer for my Arrow antenna. I've choosen the WIMO Diplexer #22030.
