In this post, I explained how I use a Wemos D1 Mini microcontroller and a MOSFET module to control the fan speed of a wired fan-aspirated MeteoShield Pro from Barani Design. I am also testing a model with a fan powered by solar panels. Both come with two additional wires connected to a reed switch…

Controlling fan speed on a Barani Design prototype fan-aspirated radiation shield
Recently, I was fortunate to receive a new prototype model of the fan-aspirated MeteoShield Pro from Barani Design. On this version, the solar panels are replaced with two power wires, making it possible to connect an external power source, allowing the fan to be active 24 hours a day. Varying fan rpm is possible by…
