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 elements that are used to measure the ambient temperature, and often also other physical quantities, such as air humidity or atmospheric pressure. This type of sensors requires a digital circuit to read the measured data, so it is used in projects that use communication interfaces that support such elements (e.g. I2C). The advantage of digital temperature sensors is high precision of operation, attractive price and convenience 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 installations and air conditioning systems. This type of sensors is also often used as an element of building automation systems and smart home installations - thanks to constant access to data on the temperature in individual heating zones, it is possible to constantly adjust the intensity of heating or air conditioning. This allows you to minimize the amount of energy needed to achieve thermal comfort, which reduces the costs of operating the building. Digital sensors work exceptionally well with control systems that rely on this type of communication, which is why they are perfect for connection, for example, with the popular Raspberry Pi minicomputer.
What to pay attention to when shopping?
Digital temperature sensors and modules that measure temperature and communicate via digital interfaces are available in many variants, which are characterized by various technical parameters that determine their application. To select the right model for a specific project, it is worth paying attention to several important factors and features - including measurement range, sensor accuracy, mounting method, communication interface and power supply parameters. The temperature measurement range of digital sensors is usually similar to analog sensors and is usually in the range from -70°C to 150°C, although models are also available that can measure up to 800°C. If your project assumes the use of an integrated sensor or module and measurement of more than one value (for example, atmospheric pressure, carbon dioxide content in the air or humidity), you should check whether the measurement ranges of these values also agree with the assumptions. The accuracy of a digital temperature sensor is usually from ±0.1°C to ±3°C - however, it is worth remembering that it may depend not only on the selected sensor model, but also on other factors, for example the transducer used. It is also very important to choose a model that supports the selected communication interface and allows for convenient installation. The sensor's power supply parameters must be within the range specified by the manufacturer - otherwise the sensor will not function properly and may even be damaged, for example by being supplied with too high a voltage.
What products will you find in this section?
In this category, we offer digital temperature sensors for installation in through-hole technology (THT), integrated sensors enabling the measurement of many values at the same time (temperature, air humidity, atmospheric pressure or carbon dioxide) and modules from popular manufacturers (including the Grove, iNode and Iduino series). intended for use in electronic projects. They communicate, among others, via frequently used I2C or SPI buses, making them perfect as an element of devices such as self-built weather stations or air quality control systems. Ready-made electronic thermometers and weather stations, temperature sensors equipped with measurement probes, digital infrared temperature sensors and many other products are also available. We encourage you to familiarize yourself with our offer of digital temperature sensors, as well as the remaining range available in the Botland online store.
Digital temperature sensors - FAQ
The way digital temperature sensors work depends on the specific type of sensor. Digital temperature sensors are often used to measure the temperature in electronic devices (they provide protection against overheating and, consequently, damage to the protected parts of the system). Some sensors intended for precise temperature measurement use silicon measuring elements. The measurement process is usually based on the voltage relationship (emitter-base) or the voltage difference between the transistor junctions. As the temperature increases, the voltage between the base and emitter decreases. In turn, a drop in temperature causes an increase in voltage.
The choice of a temperature sensor should, first of all, be appropriately adapted to the specific application (how the sensor is used). When choosing a sensor, you should pay attention not only to the measurement range, which should be adapted to our expectations, but also to the measurement accuracy. Other important factors determining the choice of a temperature sensor are the installation method, power supply parameters, and the interface responsible for communication.
The most common symptoms of a damaged liquid temperature sensor include incorrect readings (too high or too low). Additionally, damaged sensors sometimes show correct temperatures and sometimes incorrect ones.
