Mobile and Wearable LoRa-based Smart Farm Produce Tracking System

Due to erratic or nonexistent internet and mobile network connectivity, micro, small, and medium-sized companies (MSMEs) in many rural and impoverished locations have significant difficulties tracking the movement of agricultural products throughout transit. In these conditions, traditional GPS-GSM systems malfunction, leading to blind spots, transit losses, and decreased supply chain accountability. We suggest and put into practice a low-power wide-area network (LPWAN) based LoRa agricultural produce tracking system in order to solve this problem. at order to provide continuous monitoring, even at faraway locations, the system combines an ESP32 microcontroller, a GPS module for precise location tracking, and an OLED display for real-time visual output. A LoRa SX1278 module handles data transmission. Bluetooth data export for mobile access and SD card logging for offline storage are extra features. With a communication range of more than 5 km in open spaces, a packet delivery ratio (PDR) of 8595% in various terrains, and a 48-hour continuous operating life on a 2200 mAh battery, field tests confirmed the system’s efficacy. By offering a dependable and scalable platform for traceability in agricultural supply chains, this reasonably priced, flexible, and energy-efficient solution lowers transit losses, improves transparency, and strengthens the position of rural MSMEs.
