AN-1142 Bat Detector – Ultrasound Translator

In many cultures, bats are perceived as bad omens, as symbols of death or as manifestations of bloodsucking vampires. This may have arisen from the fact that a few species (eg. vampire bats) feed from cattle and can carry biological agents. However, in reality, bats are helpful creatures that play an important role in pollination, spreading seeds, and in providing a natural pest management service. A Bat Detector can notify us about the presence of bats, along with assisting in the analyzing of the groups of bats, in a certain area. This application note will explain the implementation of a circuit using Silego’s GreenPAK devices to process the ultrasonic signals produced by the sounds that bats emit.
