Sensor notes
2610 ozone sensor
Ozone is used, because of its oxidizing properties, in a variety of applications to clean and decontaminate air and water. These applications include water treatment, air purification in smoky environments, and home air cleaners. Since ozone is hazardous to human health, its concentration needs to be monitored so that it does not exceed around 0.1 ppm in livable spaces. Mics 2610 is highly responsive to ozone and robust enough to be used in industrial devices.
5135 Ethanol
Measurement of the blood alcohol content (BAC) by correlation with the alcohol in breath is common practice by the police to determine if a person is driving under the influence of alcohol. Using the 5135 alcohol sensor, a personal alcohol tester can be built at low cost, so that individuals can test their own approximate BAC level by simply blowing on the sensor. Such devices should not be used as a license to drive after drinking.
5524 CO/HC
This sensor measures CO and hydrocarbons. Its SMD package makes integration on a PCB very cost-effective.
