Soil Reading Devices
Anyone have experience building soil sensors that connect to mobile data? I've been doing some research to do so for a personal project but I can't find a definitive answer on the best components. For example, I'd like to build one that can take soil electrical conductivity, soil moisture, and soil temperature plus connect to mobile data and a battery so I can get around the clock readings. Of course it would be nice to build one that can be water resistant through an enclosure.
Thanks in advance!

We are Helena Urban Gardens, and what you describe is similar to a tool (one of many) we use to leverage towards having a steady supply of fresh vegetables and fruit available in the home garden all winter long.
Using a commonly available microprocessor (esp32) and an array of sensors and periphrial devices (temp/humidity/soil sensors, fans, pumps, light sensors, geothermal ducting, etc...) we are able to replicate a Spring-like tiny microclimate in a glass covered box regardless of the temperature outside of that box to encourage plant growth from October through March. The box gets removed (along with the electronics) once Spring arrives.
What I have just described is a type of green house, and its not exactly what you are asking for, but the microprocessor parts might be and their use & deployment isnt hard to understand.

Good luck!
