The rain gauge (or pluviometer if you’re fancy) needs extra calibration to adjust for how much water the buckets take on before tipping.Īn ESP32, with additional level shifters and BMP180 atmospheric pressure sensor module, are placed in a junction box. The rain gauge uses a “tipping bucket” mechanism, with a magnet attached to it that triggers the hall sensor affixed to the frame.
The 3D printed anemometer uses a hall sensor to detect the revolution speed of the device. A mostly 3D printed wind vane is printed with the base attached to a ball bearing and magnet so that the four hall sensors positioned in a “plus” configuration at the base can detect direction. has been working on various parts of the weather station, including the rain gauge and anemometer, with the weather station build incorporating all these past projects and adding a few extra features for measurement and access.įor temperature and humidity, a DHT22 sensor is located in a 3D printed Stevensen screen, giving the sensor steady airflow while protecting the module from direct sunlight and rain. Creates a DIY weather station to measure rain fall, wind direction, humidity and temperature.
