Smoke detector

Dartmouth University's new device (USA) can immediately detect nicotine levels in the air that affect non-smokers.

Equipment to help catch people at the battle of air pollution by smoking

Parents who have a habit of smoking but do not want their children affected by smoke often choose to release smoke in an open window or go outside.

However, is this action sufficient to protect your child from the risk of passive smoking? With Dartmouth's new device (USA), users can determine it right away.

With matchbox size, this device is equipped with a sensor with a polymer plate that captures nicotine molecules floating in the air.

When these molecules come into contact with the polymer plate, the electronic signal will be activated and sent to the device's tiny processor. From there, the information will be shot through the smartphone or computer using a wireless connection to read the results immediately.

The polymer is sensitive enough to capture molecules at billionth size. The device can even show exactly how many cigarettes the nicotine content in the air is.

Because the device is designed to update data continuously, it is easy to predict the amount of nicotine inhaled by non-smokers as they are around.
