Interesting facts about temperature & humidity sensors
Indoor comfort is strongly influenced by humidity-air that s too dry can feel cooler and less comfortable, while high humidity often makes rooms feel warmer and can increase condensation risk. Having a sensor that tracks trends (not just current values) helps you spot patterns like nighttime humidity spikes, ventilation needs, or heating-related dryness, so you can adjust habits or automation more effectively.
