What to Odor Sensor react to ?
Odor Sensor reacts to tobacco smole, motor exhaust,
odor emitted from animals, etc.
Odor Sensor reacts to tobacco smole, motor exhaust,
odor emitted from animals, etc.
Allergen sensor an Odor Sensor also may react to
vapour of insecticides, cosmetics, alcohol, hemicals
and the like, and to extreme change of temperature /
humidity.
(2) Detection of the air contamination by the fluctuation ratio of sensor resistance
vapour of insecticides, cosmetics, alcohol, hemicals
and the like, and to extreme change of temperature /
humidity.
(2) Detection of the air contamination by the fluctuation ratio of sensor resistance
The output voltage from the odor sensor is input into the indoor unitÅfs microcomputer to detect the air
contamination.
This method detects the air contamination by converting sensor output voltage into the sensor resistance value
and calculating its fluctuation ratio per unit of time. Therefore, the sensor determines that the air is contaminated
when the sensor resistance value drops abruptly.

(3) Operation of the indoor unitÅfs microcomputer
When the air conditioner is plugged in, the indoor unitÅfs microcomputer starts operating and, after 1 minute,
starts detecting the air contamination.
starts detecting the air contamination.
(4) Switching sensitivity of the odor sensor
The sensitivity of the odor sensor can be adjusted when the sensor is too responsive or unresponsive.
It is set as standard at the factory.
Sensitivity is divided into three levels: high, standard, and low.
The contamination is detected when the sensor resistance drops below following percentages compared to the
reference value in a clean state.
(This is equal to the description of the resistance of the allergen sensor.)

(1) Outline of the optical allergen sensor
(1) Outline of the optical allergen sensor
As with the odor sensor, this sensor is used to display the clean sign during the operation. The pulse signal is output
from the microcomputer into the basic circuit show in the figure below, and the sensor signal is input into the
microcomputer according to the size or amount of the dust.
