| How the Sensor works | ||||
![]() |
Steps: | |||
| 1: | Oxygen in the atmosphere and electrons in tin oxide are combined, making it difficult for electrons to flow. | |||
| 2: | Blowing on the sensor with alcohol gas, | |||
| 3: | Alcohol gas replaces the oxygen on the sensor surface where electrons are bound | |||
| 4: | Alcohol gas absorbs the oxygen and separates it from electrons. | |||
| 5: | Electrons separated from oxygen change to a state where it is easy to flow, and this change in resistance value is used to measure the alcohol concentration. | |||
| Elements:; | ||||
| A: Tin oxide/Sensor | B: Oxygen | C: Gas | ||
Supports straw method and open blow method 2-way measurement
