On the application of IoT: Monitoring of troughs water level using WSN

The need of monitoring the water level of troughs is increasing. This is parallel with the growing of Wireless Sensor Network and Internet of Thing. By combining both approach, cattlemen can monitoring their troughs ubiquitous using their own personal device. This paper develop such system by using LoRa™ as the media between sensor hub and nodes, while Raspberry Pi is used as the gateway to push data into server. We have successfully tested the functionality of node to hub join mechanism, where a node should join to the closest hub, which marked by the highest RSSI of beacon signal. The designed system is able to wirelessly sense trough water level up to 50 simulated nodes.
