In this video, I'll explore several different methods for measuring soil moisture, including gravimetric, neutron probe, tensiometer, time domain transmissometry, time domain reflectometry, capacitive, and resistive methods. I'll explain how each method works and discuss their advantages and limitations.

I'll also show you how to make your own DIY soil moisture sensor PCBs for the capacitive and resistive methods. For the capacitive sensor, I'll be using an MSP430 microcontroller and for the resistive sensor, I'll be using an ATtiny13A microcontroller. I'll go over the design and assembly process step-by-step, and provide all the necessary code and schematic files.

Whether you're a gardener looking to optimize your watering schedule, a farmer managing large-scale irrigation systems, or a student or researcher studying soil moisture dynamics, this video will provide valuable insights and practical knowledge for measuring soil moisture using different methods and building your own custom sensors.
