Types of Temperature and Humidity Sensor

 
 
01
 

Capacitive humidity sensors

These types of sensors provide stable readings and can detect a wide range of relative humidity.

 
02
 

Resistive humidity sensors

Unlike the capacitive humidity sensors, these sensors can operate in remote monitoring applications where the distance between the signalling circuit and sensor element is large.

 
03
 

Thermal conductivity humidity sensors

These sensors are used to calculate absolute humidity. Thermal conductivity sensors are durable and ideal to use in corrosive or high-temperature environments.

Applications of Temperature and Humidity Sensor
 
01/

Hvac systems

One of the major uses of temperature and humidity sensors is in hvac systems. These systems maintain the quality of the indoor air, regulating the temperature and the moisture level. In commercial settings, the sensors work by adjusting the heating and cooling based on occupancy, promoting comfort and efficiency.

02/

Agriculture & greenhousing monitoring

The crop’s health depends a lot on the temperature and humidity. The precise temperature will lead to proper yield, enhancing the quality of the output. The equipment helps the farmers monitor the farm. The excess humidity May lead to fungal growth, and the high temperature can create drought-like conditions.

03/

Industrial manufacturing process

In most industrial environments, especially those involving pharmaceuticals, chemicals, and electronics, need specific temperature regulations. Even a small temperature variation can lead to material degradation, product defects, and equipment malfunction.

04/

Data centres

The servers in the room filled with computers release a lot of heat, and thus, it is vital to have strict environmental control. The excess heat can damage the hardware. On the other hand, humidity can lead to electrostatic discharge or corrosion.

05/

Smart devices

We are living in the age of the internet, where everything is automated and integrated with iot (internet of things). Many of the consumer devices are now integrated with temperature sensors, which enhance the functionality and the user experience.

06/

Healthcare systems

When dealing with the products of the healthcare system, having a controlled environment is essential, especially for storing the vaccines, medicines, and laboratory samples.
