Development and Performance Evaluation of a Low-Cost IoT Telemetric Soil Moisture and Nutrient Sensor for Smallholder Farms

Precision farming technologies remain cost-prohibitive for smallholder growers. We present the design, firmware calibration, and field validation of a solar-powered capacitive soil moisture and NPK electro-conductivity probe operating over LoRaWAN.
