What type of sensors do breathalyzers use?
There are several different types of sensors that are used in commercial breathalyzer products. The most common is the oxide semiconductor sensor, which uses voltage differences between capacitors to determine the level of alcohol in a breath sample. Oxide semiconductor sensors are reliable, accurate and relatively inexpensive to manufacture. Another common type of sensor is the fuel-cell sensor, which uses a compact fuel-cell to evaluate a breath sample for alcohol content. A fuel-cell can provide longer-term reliability, as fuel-cell technology can handle more rigorous applications than oxide semiconductors. However, fuel-cell sensors are more expensive to produce, and this is reflected in the cost of devices. Fuel-cell sensors and oxide semiconductor sensors have generally equivalent accuracy.
