Temperature sensors - measuring temperatures accurately and reliably

With a temperature sensor, you'll always have an accurate and reliable measurement device on hand to help you optimize and monitor your processes. These devices are easy to install and operate, and offer you a wide range of functions and options to personalize your measurements and adapt them to your requirements. Temperature sensors can be found in many everyday applications these days. Some examples are: Air conditioners and heaters, cooling systems, Electronic devices such as computers, smartphones and tablets to monitor operating temperature. Temperature sensors can also be used in many household appliances such as washing machines, dryers and dishwashers to measure the temperature of the water. We invite you to browse our selection of temperature sensors and find the perfect device your needs. Each sensor has been carefully selected to ensure high accuracy and reliability in every measurement. Buy your temperature sensor today and experience the benefits of accurate and reliable measurements.

What are temperature sensors?

Temperature sensors, also called temperature probes, are devices that are capable of measuring temperature. They can measure both heat and cold. They are used in many different industries and applications, from monitoring room temperature in homes to monitoring critical process temperatures in industry. There are different types of temperature sensors, such as thermistor, RTD (resistance thermometer), and IC sensors.

How does a temperature sensor work?

Most temperature sensors work on the principle that the electrical conductivity or resistance of a material changes with changes in temperature. The sensor measures these changes and converts them into an electrical signal that can then be evaluated by a controller or microcontroller.

Which temperature sensors are available?

There are different devices that are used to measure and monitor temperature in different environments. Environmental sensors are sensors that are specifically designed for use in the environment. They can measure temperature, humidity, light intensity, air pressure and other environmental conditions. Thermocouples are electrical components based on the Seebeck effect. They generate an electrical voltage that is measured in proportion to the temperature difference between two terminals. Temperature transmitters (also called temperature transducers) are electronic devices used to convert a measured temperature into an analog or digital signal that can be interpreted and used by a measuring device or control unit. They are typically part of industrial process control systems and are commonly used to monitor temperature in various applications such as heating, ventilation, air conditioning, chemical processes and manufacturing equipment. Temperature sensors are devices specifically designed to measure temperature. They can come in many different shapes and sizes, including thermal resistance, thermistor, and thermocouple.

What (maker) projects can you do with them?

The possibilities with temperature sensors are endless! For example, you can build a controller that maintains a certain room temperature. Build an oven where you can monitor and control the temperature. Or build your own weather station with a local display! There are many IoT projects where temperature sensors can be used. Temperature sensors can be used to monitor and regulate room temperature. But they can also be used to monitor the temperature in a refrigerator or freezer to make sure food is stored at the right temperature. Temperature sensors are also interesting for pet owners, for example to monitor the water temperature in aquariums. To monitor the temperature in a greenhouse to ensure that plants are growing in optimal conditions. There are many other applications where temperature sensors can be used for control. The use often depends on the specific requirements of the project.

What should you consider when buying?

If you're looking to buy a temperature sensor, there are a few important factors to consider. First, consider what project you want to use it for. Some sensors are better suited for high temperatures, others for low. You should also make sure that the sensor provides the accuracy you need and that it is compatible with your electronics. In summary, temperature sensors are an important part of many Maker projects. With them you can realize a variety of applications from monitoring room temperature to monitoring critical process temperatures. It's important that when you buy the sensor, you look at its accuracy, compatibility and suitability for the project you want to do. With a temperature sensor, you have the ability to turn your ideas into reality and take your projects to the next level!
