The device runs on a simple battery and except for the microprocessor and sensor, most of the parts can be obtained from a local electronics store. BelBruno told Discovery News that the sensor could be mass-produced in a way that would make it easy for the consumer to replace the polymer sheets.
For parents, such a sensor would be a way to open up the conversation about how much a parent's habit can affect his or her kid. For instance, readings from the sensor could show that smoking by the window isn't reducing the amount of dangerous nicotine in the air. "There's even some infiltration when you're out on the porch," he said. "So maybe someone would go to the end of the driveway." BelBruno said support for the research came from both pediatricians and cancer researchers.

Another use is in hotels. Hotels usually just charge people if they suspect they've lit up in a non-smoking room. But it's the customer's word against the hotel staff and the customer is always right, yes? Since this sensor can measure nicotine concentrations over time, it isn't hard to correlate the increase with when a given person was in the room (or not).
