With the Aenmosens_MCU board, it is possible to use Anemosens as a stand-alone anemometer that can be used for long-term observations in remote areas (hence the microSD card slot) or as another part of your weather station (hence the RS485 interface).<\/p>\n\n\n\n

The RS485 interface is used to provide the measurement data via Modbus. In this way, you can easily connect the anemometer to your RaspberryPi, PC or many other platforms that support RS485 or Modbus. <\/p>\n\n\n\n

In addition, a serial stream of the data (packaged as a handy JSON) can be activated via the USB port.<\/p>\n\n\n\n

Last but not least, the built-in ESP32 also starts a BLE server. This also gives you the option of accessing the data wirelessly using your smartphone or computer.<\/p>\n\n\n\n

Of course, you can also write your own firmware and program it via the integrated USB-C port. The QWIIC port makes it easy to connect additional sensors via I2C. <\/p>\n\n\n\n

I bought the board from the board manufacturer PCBWay.com<\/a><\/em><\/strong> which has provided me with these free of charge. At this point, thank you again for the great service and cooperation \ud83d\ude42.<\/p>\n\n\n\n

In the following you can see a few pictures of the finished board and (almost) all possible components. Unfortunately, some sensors such as the BME280 are very expensive or poorly available due to the current chip shortage, which is why I have not installed it.<\/p>\n\n\n\n
