目的：利用物联网和云计算技术实时监测和控制水箱/水池的水位，以避免水箱/水池中的水的浪费。方法/分析：利用类似雷达/声纳原理的HC-SR04超声波传感器检测水箱中的水位，将电能转化为声波，反之亦然，并与德州仪器的CC3200 LaunchPad芯片Wi-Fi微控制器接口。使用地理标记技术可以轻松跟踪溢水的位置。研究结果：超声波传感器测量距离，微控制器读取数据并上传到ThingSak云中进行实时监控和图形表示。当水到达预留位置时，正常情况下马达将关闭。一旦水达到最大水位，就会发生溢流。如果电机执行器(继电器)发生故障，则需要对电机进行物理切换。这种情况是通过使用GSM SIM900A(全球移动通信用户识别模块)向手机发送警报来解决的，因此，执行器的故障被排除在外。新颖性：在本研究中，我们设计了一种基于物联网的最低功耗水位指示器，可用于家庭应用。

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.
