Digital temperature sensors allow to perform more complex measurements and work with the already obtained measurements may be easier than in the case of analog counterparts. The output signal of the digital sensors is transmitted as a string of bits, and their interpretation will need some digital layout.

Digital temperature sensors
Digital temperature sensors are electronic components which are used to measure ambient temperature and often other physical quantities such as air humidity or atmospheric pressure. This type of sensors requires a digital system to read the measured data, therefore they are used in projects using communication interfaces that support such elements (for example I2C). The advantage of digital temperature sensors is high precision of operation, attractive price and comfort of use, as well as easy cooperation with popular minicomputers such as Raspberry Pi.
Where are digital temperature sensors used?
Digital temperature sensors are commonly used in devices that require measurement of this physical quantity. These include, among others, household appliances, thermometers, weather stations, heating systems or air conditioning systems. This type of sensors is also often used as an element of building automation systems and intelligent house installations - thanks to constant access to temperature data in individual heating zones, it is possible to adjust the intensity of heating or air-conditioning on an ongoing basis. This allows to minimize the amount of energy needed to achieve thermal comfort, which reduces the costs associated with the operation of the building. The digital sensors work extremely well with control systems that rely on this type of communication, which is why they are ideal in combination with the popular Raspberry Pi minicomputer, for example.
What to pay attention to when shopping?
Digital temperature sensors and modules measuring temperature and communicating via digital interfaces are available in many variants, which are characterized by different technical parameters that determine the application. In order to select the right model for a specific project, it is worth to pay attention to several important factors and features - including the measuring range, sensor accuracy, mounting method, communication interface or power supply parameters. The temperature measuring range of digital sensors is usually similar to that of analogue sensors and ranges from -70°C to 150°C, although there are also models available to measure up to 800°C. If your project involves using an integrated sensor or module and measuring more than one value (for example, also atmospheric pressure, carbon dioxide content in the air or humidity), you should check whether the measuring ranges of these values also match the assumptions. The accuracy of a digital temperature sensor is usually between ±0.1°C and ±3°C - however, it is worth remembering that it may depend not only on the chosen sensor model but also on other factors, for example the transmitter used. It is also very important to choose a model that supports the chosen communication interface and enables comfortable installation. The power supply parameters of the sensor must be within the range specified by the manufacturer - otherwise the sensor will not work properly and may even be damaged, for example, due to power supply with too high a voltage.
What products can you find in this section?
In this category, we offer digital temperature sensors for installation in the threaded technology (THT), integrated sensors enabling measurement of multiple values at the same time (temperature, air humidity, atmospheric pressure or carbon dioxide) and modules from popular manufacturers (including Grove, iNode or Iduino series) designed for use in electronic projects. They communicate through, among others, frequently used I2C or SPI buses, thanks to which they are perfect as an element of such devices as self-built weather stations or air quality control systems. There are also ready-made electronic thermometers and weather stations, temperature sensors equipped with measuring probes, digital infrared temperature sensors and many other products. We encourage you to familiarize yourself with our offer of digital temperature sensors, as well as other assortment available in Botland online shop.
