Elephants will be protected by acoustic firing sensors

Installing GPS beacons on the largest land animals on the planet allows you to track their movement, but not the fact of an attack by poachers. And since they do not want to compromise, African rangers have enlisted the support of American scientists. They designed sensors that respond to the sound of a hunting weapon.

The sensor works in conjunction with a GPS beacon, and if the elephant is fired upon, the coordinates of the scene will be immediately displayed on the ranger's tablet. The technology is called WIPER and is designed specifically for exploitation in the wild. The acoustic sensor is tuned to pick up and recognize the sound wave from firearms, both conventional and silenced.

The radius of the guaranteed action of the sensor is only 50 m, so this device will not save elephants from a sniper's bullet. And it is not too reasonable to attack such a well-trained bandit - for these purposes, police special forces and other methods of work are used. The calculation is made on the ability to quickly figure out poachers and hooligan hunters who like to shoot at animals for fun.

One sensor, in theory, can cover a small herd of elephants, since these animals live together and keep close together. The battery life is one year, but WIPER sensors are specially designed on an open platform to ensure compatibility with different GPS modules and expand their potential. Ideally, forest services from different countries will be able to purchase arbitrary models of trackers, connect acoustic sensors to them and supply their ward animals with this type of alarm.

The first field trials of the new technology will take place this summer in Northern Kenya.
