Anemometer
This project started as a project in DTU course 62547 Embedded C/C++ Smart Applications which I attended at my fourth semester in the spring of 2021. Initially the project consitsted of an anemometer part and a basestation part which both were based on a PIC24 microcontroller and a NRF24L01 radio communication module. The basestation had furthermore an ESP8266 microcontroller for transmitting data to a SQL server.
DHT22 temperature and humidity sensor housing
Now I have simplified the system so that I use an ESP8266 microcontroller directly connected to the sensor. Because the ESP8266 is more than enough capable of handling a sensor and transmitting data via WiFi to a SQL server and now after finishing the course, using a PIC MCU is no longer mandatory. The only downside is that every sensor has to be in range of WiFi. Fortunately that is not a problem on my property.
