Temperature, relative humidity, atmospheric pressure and VOC interior sensor with RS 485 (MODBUS) output - STHPV 102 is designed to measure air temperature, air relative humidity, atmospheric pressure and concentration of VOC (volitale organic compounds) in the air in spaces protected against water. This combined temperature, relative humidity, atmospheric pressure and VOC sensor STHPV 102 consists of a plastic ribbing head, where a printed circuit board with the individual sensors and a converter is placed to establish a communication via the RS 485 bus. Temperature, relative humidity, atmospheric pressure and VOC are measured by a common internal sensing element whose signal is processed in a microprocessor and is converted to an output signal of MODBUS RTU. 

Temperature, relative humidity, atmospheric pressure and VOC sensor - STHPV 102 meet ingress protection IP 30 according to EN 60529 standard, as amended. Suitable design and high-quality material ensure that the sensors do not feel disturbing even in the interiors with high aesthetic requirements. You can choose the color of the box white or gray. The installation is recommended on an inner wall at the height of 1.5 m, in areas with moving persons, not exposed to direct sunlight and not influenced by heat from walls, heat sources or lighting. 

Temperature, relative humidity, atmospheric pressure and VOC sensor - STHPV 102 is designed to be operated in a chemically non-aggressive environment; the use must be chosen with regard to the temperature and chemical resistance of the sensor head and of the individual sensors.

The operating conditions to establish the correct function are:

  • ambient temperature around the sensor: - 30 to 70 °C, for short period -40 to 80 °C
  • relative ambient humidity: 0 to 95% (non-condensing humidity)
  • atmospheric pressure: 87 to 110 kPa        

DECLARATIONS, CERTIFICATES, CALIBRATION

  • Manufacturer provides EU Declaration of Conformity.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
