Sense
Mill Sense measures:
Too high levels of humidity can cause mold growth which is harmful for your
health, as it can cause asthma and allergies. It is therefore crucial with good
ventilation when taking a shower, drying of clothes and cooking. The recom-
mended level of humidity: 30-60%. A humidifier / dehumidifier can be a
solution to achieve a recommended humidity level in the home.
• Max Accuracy: Relative humidity sensor ±2.0% RH
Humidity
TVOC
• Alcohols
• Aldehydes
• Ketones
• Organic Acids
• Amines
• Aliphatic and aromatic hydrocarbons
Temperature
A consistent temperature in all rooms are important for a healthy indoor
climate. It is not recommended to turn the heat completely off in rooms
you are not using for instance, as in combination with humidity this can
cause mould growing. Temperaure affects performance, comfort level
and cold or flu symptoms. Connect Mill Sense to Mill WiFi heaters for
more precise temperature control. *This way the temperarure will
automatically adjust to your daily routines. Recommended temperature:
18-25°C.
• Max Accuracy: Temperature sensor ± 0.15°C
The eCO2 measurement is calculated from the VOC measurement. The
calculation makes some assumptions about the percentage of VOCs that are
due to CO2 . If there are substantial concentrations of other VOCs present,
the eCO2 reading would be higher than the actual CO2 level. Moderate to
high levels of carbon dioxide can cause headaches and fatigue, and higher
concentrations can produce nausea, dizziness, and vomiting. Loss of
consciousness can occur at extremely high concentrations. Good ventilation
and regular ventilation are important to maintain a recommended eCO2 level.
Recommended eCO2 level: <1200 ppm.
eCO2
Total Volatile Organic Compounds are airborne chemicals
& toxins emitted from everyday items such as paint, furniture and clean-
ing products. They can be harmful at a high concentration, causing
irritations in eyes, nose and throath. Depending on the level and length of
exposure it can also cause more serious damage to liver and kidneys.
Recommended TVOC level: <220 ppb. An air purifier will be able to
ensure that the TVOC level is within the recommended level. Mill Sense
measures the following VOC’s.
*Mill Sense is not compatible with Mill WiFi generation 1 heaters.
