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 […]

Reading a PT100 sensor with a Wemos D1 Mini
In my never ending quest for better temperature readings – or other ways of doing so, at least – I’ve begun trying other sensors than the SHT35. One of them is the PT100. It’s supposed to be very accurate. It it used in many different situations, from laboratory settings to industry. It’s also used in […]
Project Apogee part 3: controlling the TS-100
In my previous post I addressed the power supply needed to run the Apogee Instruments TS-100 fan aspirated shield in my setup. The next step is building a controller for the fan that allows me to vary the fan speed and read the actual rpm being achieved. The idea is that the controller can query […]
