Water bodies have seen a rise in chemical pollutants in recent years. Therefore quality testing has become an essential part of treatment. Currently in India, monitoring of water quality is done by physically going to water bodies and collecting samples which are then sent to be tested in laboratories. This is time consuming and inefficient method. To automate this process, water quality monitoring...

Temperature has a strong impact on the operations of all electrical and electronic components. In wireless sensor nodes, temperature variations can lead to loss of synchronization, degradation of the link quality, or early battery depletion, and can therefore affect key network metrics such as throughput, delay, and lifetime. Considering that most outdoor deployments are exposed to strong temperature...
Temperature strongly affects the operation of integrated circuits, and its impact has been largely investigated on a device level. However, the impact of temperature variations on networks of multiple devices is far less understood and requires investigation.
