High-precision temperature sensors

High-precision temperature sensors allow the measured temperature to be determined with high accuracy (for example, in the range of ±0.1°C), so that they can be used in devices and measuring instruments that require meticulous measurements. Typically, high-precision temperature sensors are made using digital technology, which means that they give the result using a binary signal at the output and a digital system (microcontroller) is needed to read the data from the sensor, although there is also a large selection of analogue sensors and analogue-digital modules available on the market. High-precision temperature sensors can be contact or non-contact - in the case of the latter, the most commonly used measurement technology is infrared radiation detection, and measuring devices with built-in sensors of this type are marked as IR (English infrared).

Application of precise temperature sensors

High-precision temperature sensors are used wherever it is necessary to obtain an accurate and reliable measurement result. They are therefore used in medical and sports equipment such as thermometers, non-contact temperature control systems, athletic bands and lubricants. Precise temperature measurements are also essential for safety systems in sensitive and expensive electronic devices, which can be disturbed even with slight fluctuations of this medium. For this reason, high-precision thermal sensors are also used in factories, electronic workshops and industrial plants. They are also an indispensable part of the equipment of all kinds of laboratories and research laboratories. High measurement precision is an advantage even in less demanding applications, so such sensors are also ideal for home thermometers, room temperature controllers, weather stations, underfloor heating systems, intelligent building systems or cooling systems in electronic devices.

How to choose the right model?

When choosing precise temperature sensors, it is good to pay attention to several basic properties, which include, among others, the measuring range and accuracy of a given model, adaptation to the desired communication interfaces, the way and parameters of the power supply, the presence of additional functions or the installation method. Precision sensors typically have a measuring range of -40°C to 125°C (although high temperature sensors are also available, up to 800°C), while their accuracy depends on the model chosen and ranges from ±0.1°C to ±2°C. It is worth remembering that the measurement precision depends on external factors - including the measured temperature value (the most accurate results are obtained in the middle range of the measuring range) and the appropriate power supply, as well as the method of signal processing (for example, transducers used). Popular methods of communication in sensors and precision modules include I2C or SPI. The matching of the appropriate power supply is also a very important selection factor - otherwise the obtained measurement results may be inaccurate and the whole sensor may even be damaged. It is also worth noting the presence of additional functions, such as air humidity measurement or atmospheric pressure measurement - they are particularly useful in projects involving the control of more than one medium at a time (for example, in weather stations).

What do you find in our assortment?

In this category we offer a wide range of precise temperature sensors and measuring modules. Here you will find products of popular companies such as Adafruit, Seeedstudio, SparkFun or iNode. Models with a temperature measurement function are available, as well as with an additional possibility to measure air humidity or atmospheric pressure level. We offer modules with goldpin and Grove connectors as well as wireless variants that communicate via Bluetooth 4.0. We invite you to familiarize yourself with the full range in this category, as well as with our offer of other digital and analogue sensors that you can use in your electronic projects.
