Now a days monitoring soil moisture is one of the methods used by farmers for irrigation purpose. Due to that point developing numerous sensor types and data logging systems but their widespread adoption in years for this purpose due to a number of factors, the practical schedule for irrigation is still limited. Significant Factors that limit farmers ' use of soil moisture sensing technology Include high costs and challenges in collecting and interpreting timely data. Recent developments in microcontrollers in open source (such as Arduino) Internet - of - Things (IoT) and wireless communication provide farmers with opportunities to reduce costs and facilitate timely data collection, visualization and interpretation. The aim of this study was therefore to develop and test a low cost IoT system for the monitoring of soil moisture using Watermark 200SS sensors. The system uses Arduino-based microcontrollers and field sensor data (End Nodes) is transmitted wirelessly via LoRa radios to a receiver (coordinator) that connects to the Internet via WiFi and sends data to an open source website (ThingSpeak.com). Under field conditions, the system was successfully tested by installing watermark sensors at wheat field. The system described here could contribute to the widespread adoption of easy-to - use and affordable moisture sensing technologies among farmers.
