Advances in wireless communications are creating new sensor capabilities. Current developments in the field of sensor networks are very important for environmental applications. The Internet of Things (IoT) allows connections between various devices through the ability to exchange and collect data. IoT is also leveraging Industry 4.0 to extend its capabilities not only to the automation industry but also to environmental issues. As water is one of the basic requirements of human survival, it is sometimes necessary to incorporate several mechanisms to monitor water quality. About 40% of deaths worldwide are caused by contaminated water. Therefore, there is a need to provide purified drinking water to cities and villages.
Water Quality Monitoring (WQM) is a cost-effective and efficient system designed to monitor the water quality of drinking water using Internet of Things (IoT) technology. The system proposed in this paper consists of several sensors for measuring various parameters such as pH value, turbidity in water, water level in the tank, and temperature and humidity of the surrounding atmosphere. Additionally, the microcontroller unit (MCU) that interfaces with these sensors and further processing is done on the personal computer (PC). The acquired data is sent to the cloud using an IoT-based ThinkSpeak application to monitor water quality.
The use of the ThingSpeak mobile application for water quality monitoring will be very useful to water quality board authorities. After installation, authorized users will have access to this information and will be able to view ThingSpeak data in their account using their user identification ID and password to access it. Run the app and add the channels that need monitoring. After installing the channels you want to monitor, you need to add them to your app with their channel IDs . After adding the channel ID, all graphs are displayed in the application.
