Environmental temperature is essential for security monitoring and controlled areas, such as chemicals factory and Inflammable goods vehicle, in which WSN is the most appropriate choice for intelligent monitoring purpose. In this work, we design a piezoelectric energy harvester to collect low-acceleration (<0.5 g) and low-frequency (<50 Hz) vibration energy for powering wireless sensor network...
This paper presents a novel electromagnetic-based bridge energy harvester (EBEH) utilizing bridge vibrations and ambient wind to harvest energy for wireless sensor nodes (WSNs) used for monitoring the health of bridges. The architecture, working principle, fabrication and characterization of the harvester is discussed. The harvester consists of a fixed wound coil, a permanent magnet, an airfoil, a...
Recent years has show an increase in the occurrence of natural disasters, threatening human life and property. Early warning systems could help in reducing the impact of such disasters. We have designed and deployed a real-time wireless sensor network for landslide detection, in one of the landslide prone areas in India. The current wireless sensor network for landslide detection system is real-time,...
