Temperature and humidity sensors can be found almost anywhere around us. These sensors are capable of measuring the water vapor in the air and the temperature of the environment. But how do they work and what are their different types? Continue reading this article from Linquip and we will explain everything you need to know about temperature and humidity sensors.

What are temperature and humidity sensors?
These sensors have been designed for various applications to measure the humidity as well as the temperature of the environment. They do so by finding the amount of water vapor present in the air around the sensors. The amount of moisture in the gas can be a mixture of different elements including nitrogen, water vapor, argon, etc. Since humidity can have huge effects on different biological, chemical, and physical processes, it should be measured and controlled in different industries and hence, there’s a need for these sensors to help us out.

How do temperature and humidity sensors work?
Temperature and humidity sensors have two different ways of collecting data and measuring humidity and temperature. One type measures Relative Humidity (also known as RH) and the other type measures Absolute Humidity (also known as AH). They can also be categorized based on their size. Small sensors are used for smaller purposes and larger ones are usually used for industrial applications.

Some of these sensors are interfaced with a micro-controller for measuring the related data instantaneously. For example, the DHT11 temperature and humidity sensor are one of these digital temperature and humidity sensors with Arduino as its interface. It can also use other micro-controllers such as Raspberry Pi, etc.
