Abstract
This paper presents a prototype of an Integrated Cloud-Based Wireless Sensor Network (WSN) developed to monitor pH, conductivity and dissolved oxygen parameters from wastewater discharged into water sources. To provide realtime online monitoring and Internet of Things (IoT) capability, the system collects and uploads sensor data to ThingSpeak cloud via GPRS internet connectivity with the help of AT commands in combination with HTTP GET method. Moreover, the system sends message alert to the responsible organ through GSM/GPRS network and an SMS gateway service implemented by Telerivet mobile messaging platform. In this prototype, Telerivet messaging platform gives surrounding communities a means of reporting observed or identified water pollution events via SMS notifications.

Summary
Water pollution by chemicals from municipal and industrial wastewater has become one of the public concerns in developing countries where only 8% undergoes treatment of any kind [1]. Like many developing countries, the release of untreated wastewater remains common practice in Tanzania [1] [2] caused by lack of infrastructure, technical and institutional capacity, and financing [1], highly efficient wastewater treatment technologies and inadequate water quality monitoring and control systems [3]. Wastewater monitoring in Tanzania is still based on manual practices including field visits, sampling and laboratory tests which are insufficient to satisfy the current monitoring requirements emphasizing on continuous and dynamic water pollution monitoring [5]. The emergence of WSN in environmental and monitoring and industrial monitoring provides a promising approach for continuous, dynamic and real-time wastewater monitoring. An integrated-cloud based WSN prototype is developed to monitor wastewater discharged into water sources. The community involvement in reporting pollution discharge events, via SMS notification, in the proposed system provides an added advantage to the proposed system
