A Water Level Detection: IoT Platform Based on Wireless Sensor Network

Wireless Sensor Network (WSN) has been used in various fields and for various applications. This includes environmental monitoring, volcanic activity monitoring, supporting components in order to provide a smart city, and monitoring activity in the agricultural field. The detection of water level in the river is still not able to work automatically and real-time to determine the water level of the river. This causes the locals generally do not know when the river on the river level grows higher and higher. In this study designed a water level detection sensor-based wireless network that works automatically by reading the height of the water using ultrasonic sensor and then the elevation data is sent to a website so that the public can monitor the height of the river in real time. This system was designed using two main components HC-SR04 and NodeMCU. HC-SR04 periodically transmit data of water level in real time, then NodeMCU upload this to the monitoring platform. The test results show that the design can achieve the collection and stably upload of surrounding environment data, and meet the design requirement of remotely monitoring the living environment conditions. The invention has follow advantages: small power consumption, simple structure, low cost, convenient installation and urban communities of Samarinda no longer confused to monitor the water level in flood-prone points, with this study, now everything can be monitored in real time through all kinds of gadgets.
