The PYRO sensor uses a combination of passive infrared pyroelectric technology and a high precision lens to detect a change in the detected temperature when a person passes in the range of the sensor. Thanks to its extremely high sensitivity, the sensor can detect two different people with only a small gap between them. The sensor is self-calibrating for simple installation.

A multi-purpose sensor for monitoring all types of adventure sports: The PYRO sensor is able to count many types of users: pedestrians, cyclists (MTBs, racing cycles), horseback riders, kayakers, snowmobiles, skiers, etc.

The PYRO sensor is perfectly suited to trails shared by pedestrians and cyclists. All users, even fast-movingmountain bikes, are counted using a special algorithm.

When installed at a height of 2.7 m (8'10"), the PYRO sensor can be used to count horseback riders and thus identify which trails require priority grooming.

The PYRO sensor can be installed along a river to count visitors or, as shown here (Müritz National Park, Germany), to measure the impact of canoe traffic on waterways used by migrating fish.

From the Alps to the Arctic Circle, the PYRO sensor can be adjusted for any winter sport. The PYRO-Zoom can cover the entire width of cross-country skiing trails (Finland). It can also be used to evaluate the impact of off-trail skiing on grouse montain (the Pyrenees), measure the popularity of skiing trails (the Alps) or adjusted to detect fast-moving snowmobiles.

Lodged in the bark of a tree, the PYRO sensor blends in perfectly with the surrounding environment. The logger is installed inside a housing hidden in the ground.

The PYRO sensor can be mounted on any surface (backs of trail signs, inside existing wooden posts, inside trail markers, etc.) to be hide it from view.

Eco-Counter also manufactures all-in-one posts consisting of a sensor and counting system. This solution eliminates the need for a housing and is ideal for semi-permanent counting or rocky soil.
