My project for the Fall of 2025 was the MTEC-02A soil moisture sensor from Seeed Studios. The sensor is made to be inserted or buried in the soil and returns 3 metrics: temperature, volumetric water content (VWC) and electrical conductivity (EC). A great way to track periods of drought in the Summer that occur more…

Reading RG-15 Rain Data on a Wemos D1 Mini Using SoftwareSerial
In this post I explain how I use the Hydreon RG-15 in tipping bucket mode. There I use the J1 connector and listen for virtual “tips”, analog signals that indicate a certain amount of rain has been detected. The RG-15 also has a J2 connector which allows for digital communication via a serial connection between…

During previous summers I have always been busy with temperature sensors and radiation shields. This year, I have shifted my focus to precipitation. The main reason why I find this interesting is that our warm seasons have seen quite a few dry spells over the past few years. This causes all sorts of issues, but…
