We often get asked what is the difference between humidity and moisture sensor. In short, both sensors refer to measuring droplets of liquid within a substance, but there’s a difference!
First, let’s make sure we understand humidity in a correct way.
Humidity is a measure of the amount of water vapor in the air.
Relative humidity measures the amount of water in the air in relation to the maximum amount of water vapor (moisture). The higher the temperature, the more water vapor the air can hold. Relative humidity is what your morning weather reporter would refer to.
In short, both measure humidity, but the minor terminological difference lies in the “material” where humidity is measured in.
Typically when we refer to measuring the amount of water in air we refer to humidity sensors as humidity sensors.
By a certain temperature (e.g. 21 °C) a 100% relative humidity level would mean that the air is completely saturated with water vapor. Unable to hold any more, it would rain.
If at a certain temperature (e.g. 21 °C) where there is a 100% relative humidity level, we would raise the temperature a bit, the air could consume a tiny bit more water vapor. On the contrary, if at a certain temperature (e.g. 21 °C) where there is a 100% relative humidity level, we would lower the temperature a bit, the water vapor will condense into moisture – visible on surfaces as tiny droplets.
For your reference, healthy indoor relative humidity levels are between 30-60%.
What’s the difference between humidity and moisture sensors?
In short, both measure humidity, but the minor terminological difference lies in the “material” where humidity is measured in.
Within the industry, typically when we refer to measuring the amount of water in the air we refer to humidity sensors as humidity sensors.
But if we measure the amount of water or other liquid diffused in a small quantity as vapor, within a solid, or condensed on a surface – e.g. soil – then we refer to the humidity sensor as the moisture sensor.
All Andivi humidity sensors and moisture sensors have 3 years of warranty and are made in EU.
