Flow Sensor IoT Node for Wi-Fi equipped Apartments and Gated CommunitiesAuthors: Deepak Awasthi,Azeemuddin Syed,Suresh Purini,Annesha Mazumder Conference: IEEE Sensors 2018 (IEEE Sensors 2018 2018) Location New Delhi, India Date: 2018-10-28 Report no: IIIT/TR/2018/158 AbstractWater crisis is a major issue across various cities in the world. In recent times, a considerable amount of work has been done on remote monitoring using water flow sensors. In almost all these applications either GSM/GPRS or Zig-Bee has been used for communication. In this work, we propose a resilient water monitoring system using a low power Wi-Fi module. The goal is achieved in three stages: calibration of flow sensor, design of robust IoT node with embedded power management and packaging of the complete system. The aim of calibration is to enhance the linearity range by choosing a suitable meter constant K for the turbine flow sensor. It helps to make the system adaptive to variations in pressure and flow rate. The sensor data is processed and sent to the cloud using power efficient ESP8266 Wi-Fi SoC chip. The packaging of the complete system is done to make it watertight and suitable for usage in real-life environments. By efficient real-time tracking, users can reduce bill and save water.
