The experiments validate that the proposed prototype can be used to generate upto 88.91J of energy per day. This energy is not only sufficient to power the tags to acquire and transmit locations 24 times a day to a distance of 114Km (line of sight), but also provides a surplus of at least 35.40J, which can be used to increase the frequency of position updates or to support alternative transmission protocols. Jumbonet shows the viability of long-term tracking of elephants for real time monitoring.
This device was designed to efficiently harvest as low as microwatts (μW) to milliwatts (mW) of energy generated from a
variety of sources such as solar, thermoelectric, electromagnetic and vibration energy.
The strength of energy scavenging capability of this design emerges from the capabilities of the TI BQ25504 IC.
The MSP430 MCU further extends the unit’s lifetime with it's ultra-low power capabilities. This system was formulated wi
th the intention of enabling a mechanism to log prolonged locomotion data of wild elephants to propose a solution to the Elephant Hum
an Conflict (HEC) in Sri Lanka.
During the internship at the Airport and Aviation, I undertook a project to develop a simple circuit that demonstrates the basic concept of a radar using reflected ultrasonic waves. The project was presented at the annual national exhibition "Deyata Kirula", 2013. The project involved no programmable devices.
