Development and testing of a low-cost wireless sensor network system for environmental data collection
Abstract
This project detailed the design and implementation of a low-cost wireless telemetry system for environmental monitoring. The system was based on sensor nodes with Arduino boards and 2.4 GHz nRF24L01 transceiver modules, using the User Datagram Protocol (UDP) for fast and efficient data transmission. Through an iterative methodology, two prototypes were developed: the MK1 and MK2 ones. Initial tests revealed design flaws in the MK1 version, which led to a more robust redesign in the MK2 that included a bolted casing. Final tests showed a communication range of up to 140 meters, confirming the system’s viability for use in remote environments. The findings evidenced that the project met its objectives, laying the groundwork for future scalable applications in large-scale monitoring.
