The warmer the air is, the more water vapour it can ‘hold’. Humidity is an expression used to describe the amount of water vapour present in air. This sensor measures water vapour content relative to the ambient temperature.
The Humidity Sensor measures relative humidity, which is the amount of water vapour in the air compared with the amount of vapour needed to make the air saturated at the air’s current temperature.
A reading of 100% relative humidity means that the air is totally saturated with water vapour and cannot hold any more so sweat cannot evaporate and we feel much hotter than the actual temperature. If the relative humidity is low, we can feel much cooler than the actual temperature because our sweat evaporates easily, cooling us off.
The slots in the end cap of the sensor have been designed to allow for circulation of air as this can affect response time considerably.
The SmartQ Heart Rate Sensor can be used to investigate a number of scientific experiments such as:
