Summary
Long-term indoor thermal monitoring using Internet of Things (IoT) devices reveals key environmental factors. Findings highlight the need for targeted temperature and humidity management for health and well-being.
Area of Science:
- Environmental Science
- Building Science
- Public Health
Background:
- Indoor thermal environments significantly impact occupant health and well-being.
- Limited long-term data exists on indoor thermal conditions and their relation to health effects.
- Internet of Things (IoT)-based devices offer novel capabilities for real-time environmental monitoring.
Observation:
- A year-long study in Seoul apartments utilized IoT sensors to measure indoor temperature, relative humidity (RH), and CO2.
- Detailed measurements included kitchen, living room, and bedroom conditions.
- Additional data on air velocity and globe temperature were collected during summer and autumn.
Findings:
- Outdoor temperature strongly influences indoor thermal environments.
- Indoor relative humidity serves as a reliable indicator of residents' lifestyles.
- Specific management needs identified: temperature in summer, RH in winter, and kitchen conditions during warm periods.
Implications:
- IoT devices provide a viable method for assessing personal exposure to indoor thermal risks.
- Long-term monitoring and analysis are effective for understanding complex indoor thermal dynamics.
- This approach has significant potential for application in public health and healthcare settings.

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

02:44Heating and Cooling Curves
26.1K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

01:09Thermal Stress
3.1K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...
