Product features Room temperature sensor - Digital DS18B20

Room sensor


This temperature sensor with a digital output DS18B20 - GSD 105R for interiors is designed for temperature measurement of gaseous substances in areas protected from water - e.g. for temperature measurement in rooms (schools, theaters, conference rooms, etc.), offices, interiors of residential houses or even production halls. A proper design and high quality materials guarantee efficient temperature measurement.

The temperature sensor with a digital output 1-Wire / DS18B20 - GSD 105R for interiors consists of a plastic ribbed head in which there is a board with printed circuit and a converter to establish a digital output type DS18B20.

La sensor operating temperature range is defined in the table technical parameters of the different sensor versions. The sensors meet IP 30 protection according to EN 60529, as modified. Installation is recommended on an interior wall at a height of 1,5 m, in areas of movement of people, in places not exposed to direct sunlight and not influenced by heat from walls, heating radiators or lighting.

The sensor is designed to operate in a chemically non-aggressive environment, the use must be chosen according to the temperature and the chemical resistance of the sensor head.


  • The manufacturer provides an EU declaration of conformity .
  • Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of standards and work measurement instruments is ensured within the meaning of article 5 of Law No. 505/1990 on metrology. The manufacturer offers the possibility of supplying the calibrated sensors in the laboratory (according to the requirements of EN ISO / IEC 17025) or in an accredited laboratory. 


The sensors are designed to be mounted on a wall or other horizontal surfaces. For fixing, it is necessary to prepare the required holes for mounting screws using a template (supplied with the sensor).
Before connecting the power cable, it is necessary to separate the perforated cover from the plastic base.

Remove the cover and insert the cable through the 9mm hole, apply the base to the surface and screw with two screws or bolts. The length of the fixing bolts or screws for fastening should be selected depending on the thickness of the plastic base. Connect the power cable to the terminals according to the “Wiring” section.

"Diagram ", place the perforated cover on the fixed base and lock it by clicking it. After installation and connection to the electrical measuring device, the sensor is ready for use. the sensor does not require any special maintenance. For a more detailed description of the installation, see the user manual of the sensor
