A key designed to save lives.

Rather than just a safety drive campaign, we create an innovative accessory that won´t let you drive if you had drunk.
















Technological solution.


The idea is to leave the MCU processor in a constant deep sleep mode – consuming the equivalent of a few nono-amperes – until it is woken by the microphone, which is always connected to the amplifying circuit, with a small consumption.

When woken by the microphone, the MCU judges whether there is sufficient air flow and gives their visual feedback.

Since blowing into the key always leaves behind residues, the solution was to have an automatic self-sterilizing sensor, so as not to compromise subsequent uses.
