This value is further processed into information by an electronic display.ĭetails about the project are available at: digital soil moisture meter. These probes act as sensor elements that register moisture and change it into an electric value. This project monitors soil moisture content in irrigation farms by measuring the resistance to the flow of electric current between two metallic probes. As crop production requires water at different stages and in different amounts, it is important to measure soil moisture from time to time. AVR Projects: Digital Soil Moisture MeterĪ soil moisture meter is used for indicating the water content of a given soil sample. Let’s take a look at few interesting AVR projects. These special features help students, hobbyists and engineers make innovative AVR projects. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. ATmega series are one of the types of AVR microcontrollers with features like 4–256 KB program memory, 28–100-pin package, extended instruction set, and extensive peripheral set. AVR is a family of microcontrollers developed by Atmel beginning in 1996.
