SoilSense
The SoilSense soil measurement system is intended for use by gardeners to improve their yields by improving the amount of information at their disposal. SoilSense provides temperature, moisture, and pH data from the soil and presents the data in the universally used CSV file format. Theys ystem is composed of two main parts: the probe and the receiver. The probe utilizes an ARM based microcontroller that communicates to sensors via a shared wired I2C bus, and communicates with a wireless LoRa communication module using an SPI interface. Notably, we were able to achieve a large communication range (greater than 100 meters) and year long off-grid operation of the probe (via solar panels and year-round simulation of solar conditions). Areas in need of improvement are sensor reliability and accuracy, with the majority of outstanding features being related to difficulty in integrating the designed sensors with the rest of the probe assembly.
