Environment Sensor Special contents

  • Heatstroke Risk Levels∗3

    Heatstroke risk level is determined by air temperature and humidity.
    Users can estimate the risk of heat while performing day-to-day activities.

    Reference temperature WBGT Heat stress precautions Awareness guide
    Danger
    31°C or above
    (88°F or above)    		 Dangerous heat for all activities. Especially dangerous to senior citizens, even if they are just resting. Avoid going outside and stay indoors in cooler places.
    Severe warning
    28°C – 31°C
    (82°F – 88°F)    		 Dangerous heat for all activities. Stay out of the blazing sun and be aware of indoor ambient temperature rise.
    Warning
    25°C – 28°C
    (77°F – 82°F)    		 Dangerous heat for activities that involve moderate to strenuous physical exercises. Take adequate rest periods during physical training and strenuous work.
    Caution
    Below 25°C
    (Below 77°F)    		 Dangerous heat for activities that involve vigorous physical exercises. Risk is low but still exists on the basis of vigorous exercises and hard labor.

  • Discomfort Index∗3

    The discomfort index is calculated from the air temperature and humidity to help users realize the importance of maintaining a comfortable environment.

    Discomfort index Thermal comfort
    65 – 70 Comfortable
    70 – 75 Neutral
    75 – 80 Warm
    80 – 85 Uncomfortably hot (sweating)
    85 – Severe heat
  • Discomfort Index

  • Seismic Detection

    The sensor uses Omron’s unique spectral intensity (SI) value calculation algorithm to distinguish between seismic activity and other movements. The sensor data can be used to map damage conditions by area.

    Sensing Technology
    [ Correlation between SI value and measured seismic intensity scale ]
    Formula
    SI value (or spectral intensity):
    SI value is equivalent to the magnitude of the destructive energy imposed by seismic motion on structures. SI value has a high correlation with the seismic intensity scale which helps identify seismic hazards in your vicinity.
  • Correlation between SI value and measured seismic intensity scale
    Reference example

  • VOC Detection

    The sensor allows eTVOC reading which refers to the total concentration of volatile organic compounds to help users realize the importance of maintaining a comfortable environment.

    Sensing Technology
    [ Operating principle ]
    VOC Detection Operating principle
    • Oxygen is adsorbed onto the surface of metal oxide.
    • When VOCs are emitted into the atmosphere, the gases react with the absorbed oxygen, changing its absorbed amount on the surface.
    • The change in the amount of absorbed oxygen eventually increases or decreases the surface conductivity. This mechanism allows the sensor to detect VOC gases.

    Note. VOC sensor does not identify gas types. Only outputs the total concentration of VOCs.

  • VOCs (Volatile Organic Compounds):
    VOCs include such as alcohol consumption, cigarette smoking, and formaldehyde.
    eTVOC∗2 (equivalent Total Volatile Organic Compounds):
    eTVOC refers to the total concentration of volatile organic compounds in a room environment.
