We say that in jest, but it’s far too easy to use an Arduino to ... an IR proximity sensor module to detect dirty digits, and a small submersible pump to push isopropyl alcohol, sanitizer ...

The researchers used an Arduino Uno board ... bursts of alcoholic mist across a table, where a sensor at the other end measured the alcohol content of the air. From there, the vapor was ...

The experiment used Arduino computers, an electronic spray to release the alcohol, fans to blow the alcohol along, and sensors for detecting the chemical signals and demodulating them back into text.

The Arduino takes readings from an MQ-3 Gas/Alcohol sensor was salvaged from another breathalyzer build [Phil] put together. While it has been noted in the past that this sensor is pretty ...

There's a commercial electrical sprayer (DuroBlast) that transmits the signal, and on the other side of the room there three alcohol sensors (MQ303, MQ-3, MR513) attached to an Arduino ...

By simply choosing a wireless sensor gateway for one’s favorite development platform (Arduino, Raspberry Pi or BeagleBone Black) and any of over 20 different types of wireless sensors ...
