[Test] OCIGO, the breathalyzer test connected reconciles us with the sobriety

Design and start-up

At the level of its design, the breathalyzer test OCIGO looks like a small flute with a mouthpiece removable. An LCD screen of five inches long, and a single central button are present for the ignition and the measurement. The object is presented in a casing comprising three bits and a cable for charging via micro-USB. Once loaded, it is possible to use it alone, or connected via Bluetooth to a smartphone via the dedicated application, available for free on iOS and Android. The display indicates the procedure to follow, and once the phase of preheating the past, simply blow continuously into the mouthpiece of the device for five seconds in order for the rate to appear.

Imagined by the start-up Olythe, a native of Aix-en-Provence, the breathalyzer test OCIGO works according to the principle of the spectroscopic detection infrared. Concretely, the device emits the infrared waves at the time of the test, which are then absorbed by the molecules of alcohol. The measurement of waves remaining after this absorption allows us to evaluate precisely the rate of alcohol present in the expired air. The technology would be as reliable as a blood test, and already has the certification 16280. Currently, the OCIGO is not available for sale to private individuals. Reserved for businesses, the breathalyzer that is connected is sold for 250 €, but Olythe has a project to develop a similar product (and probably cheaper) for the general public in the future. The opening of an online shop is also planned soon.


Animated by the love of investigation and hard work, it was necessary to pass at the table (or at least behind the bar) to test the object in real conditions. Once the alcohol turned on and synced with the phone, a first test to white if needed. One breath, five seconds, and the measurement is displayed on the phone. 0g before the cocktail hour, everything seems normal, serious things can begin. After a few drinks, the bac rises as quickly as the mood of the evening, and it is necessary to admit that the numbers are going surprisingly fast.

After a few beers, one or two cups of champagne, and a good digestive, the threshold of 0.4 mg/L of expired air is quickly reached. Not what drink you under the table, but enough to be banned from driving. As a reminder, the legal threshold is located at 0.25 mg/L of expired air. In addition to alert us of the danger, the alcohol also plays in educators, by proposing an explanatory graph, and uis not time limit to make enough down the rate of blood alcohol concentration, depending on whether it was intended or not eating in-between time. The tool proves to be rather efficient even if it has suffered from a few display bugs. Impossible to some time to have a time stopper is coherent, it is possible that the device has trouble to establish the time deadline when the time period runs over two days. If it is not connected to any device, the rate is displayed directly on the LCD screen present on the OCIGO.

While revealing itself to be quite educational, the alcohol OCIGO has also had the good sense not to gamifier the consumption of alcohol. Beyond 0.40 mg/L of expired air, the threshold is blocked, and simply indicates that the user is in danger if he takes the wheel. A precaution that will prevent the user from being tempted to test the limits of the object (which was obviously not our case), and seems to us rather well.
