Hands Free Door Entry System – Sonar

Hands Free activator with presence detection signal and presence detector incorporated (sonar)

Antenna to trigger receiver when a programmed tag enters within a 5 metre range. Completely independent from the receiver, it only needs power to work, making it very easy to install. When a Free Tag gets close enough to the antenna, it triggers the tag which sends a 868MHz radio signal to the corresponding receiver at a distance of up to 100 metres.

The hands free system allows the independent control of up to 28 doors or other devices, without the need to ever press a button.

In the FREE50RS version a sonar is incorporated. This device operates with ultrasound (not audible) at 42kHz. It can detect little objects at a few meters and big objects at more distance.

For a good detection of the obstacle, this has to be at an angle of 90º respect the sonar.
