Objective: To monitor and control the water level in real time using IoT and cloud computing technologies to avoid the wastage of water in water storage tanks/sumps. Methods/Analysis: The level of water in a tank is detected by using ultrasonic sensor HC-SR04 which works on the principle similar to radar/sonar by converting electrical energy to acoustic waves and vice-versa and it is interfaced with CC3200 Launchpad, on-chip Wi-Fi microcontroller from Texas Instruments. Geotagging Technique is used to easily track the location of the water overflow. Findings: Ultrasonic sensor measures the distance and the microcontroller reads the data and uploads to the ThingSpeak cloud for real time monitoring and graphical representation. When the water reaches the reserve position and normally the motor will be switched off. Once the water attains a maximum level before overflow occurs. In case failure of the motor actuator (relay) it needs a physical switching of the motor. Such a scenario is tackled by sending an alert to the mobile using GSM SIM900A (Global System for Mobile communication Subscriber Identity Module) as such, failure of the actuator is taken care off. Novelty: In this study, we have designed an IoT based water level indicator with minimum power consumption which can be used for Domestic applications.
