Abstract

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 (WSN) system, and importantly electrical management circuit (EMC) is designed to provide steady DC voltage for intermittent driving WSN to monitor environmental temperature. The experimental results show piezoelectric energy harvester can power WSN for temperature monitoring in every 19 seconds at 0.3 g acceleration and environmental resonant frequency of 29 Hz.
