Description

[0001] The present invention comprises a sensor, in particular a housing integrated, for detecting temperature and / or humidity and / or gap dimensions in a gap between an external facade element such as a balcony floor foundation and an external house facade.

[0002] US 2019 / 0 265 082 A1 discloses methods and equipment for remote sensing with data analysis. These methods and equipment have many applications, including monitoring grain quality during storage and / or transportation. This disclosure describes a method for acquiring temperature and other environmental data to describe and predict the quality of stored grain (current and future) based on numerous factors, including fumigation, ambient temperature and humidity, and the temperature and humidity of the stored grain.

[0003] DE 11 2006 000 369 T5 shows a heat detector which has a heat detection unit which detects heat in a monitoring area and a housing which holds the heat detection unit, wherein the heat detection unit is attached to the housing via a protective device which serves to protect the heat detection unit.

[0004] US Patent 2014 / 0 300 486 A1 discloses a wireless sensor device for a high-voltage environment, wherein the device comprises a housing, a control unit for monitoring one or more variables, and a power supply unit, wherein the housing is designed to minimize an electric field and the communication unit is partially located inside the housing.

[0005] German patent DE 10 2009 039 827 A1 shows that the sensor described therein has a piezoelectric measuring element connected to a housing base. The measuring element is connected to a diaphragm on one side opposite the base. The diaphragm seals the base and is subjected to a pressure to be measured. When one of the poles of the measuring element makes contact, the diaphragm rests against an electrode plate. The electrode plate conductively and positively encloses an outwardly projecting contact pin. Another pole of the measuring element is contacted via the lower housing part and / or the diaphragm.

[0006] According to the invention, a sensor for detecting temperature and / or humidity and / or gap dimensions in a gap between an exterior facade element, such as a balcony floor foundation, and an exterior house facade comprises a substantially circular housing which is lockable to the outside, preferably watertight, thus creating a lockable interior space, and at least one sensor for detecting temperature and / or humidity and / or gap dimensions in a gap between an exterior facade element, such as a balcony floor foundation, and an exterior house facade.

[0007] According to the invention, a control device records the temperature and / or humidity values ​​and / or the gap dimension recorded by the sensor, and if a critical limit value is exceeded or fallen below, the control device generates an alarm signal, thus also indicating pending repair work on or near the gap.

[0008] According to at least one embodiment, the housing is designed in the manner of a flat plate. The housing is made of a plastic or a CFRP (carbon fiber reinforced polymer).

[0009] According to the invention, the sensor comprises a piezoelectric sensor which is installed in the housing in such a way that external pressure on the outer wall of the housing is at least partially transmitted to an inner wall of the housing, and this pressure at least partially squeezes the piezoelectric crystal, which generates a current to operate the control device and / or, in addition to an energy source, such as a battery, an additional signal triggering the current flow is modulated onto the actual operating signal by the squeezing, so that the control device generates an error signal due to this deviation.

[0010] According to at least one embodiment, the piezoelectric crystal touches the inner wall of the housing, at least indirectly.

[0011] The invention described here will be illustrated in more detail below with reference to a figure and the accompanying description.

[0012] Fig. Figure 1 shows a side view of sensor 1, where Fig. Figure 2 shows a top view of a house 30 with, for example, a balcony foundation 10 and the installed sensor 1.

[0013] The Fig. 1 and Fig. Figure 2 shows the sensor 1 according to the invention for detecting temperature and / or humidity and / or gap dimensions in a gap between an exterior facade element such as a balcony floor foundation 10 and an exterior house facade 11, a substantially circular housing 20 which is lockable to the outside, preferably watertight, thus creating a lockable interior space, and at least one sensor 1 for detecting temperature and / or humidity and / or gap dimensions in a gap between an exterior facade element such as a balcony floor foundation 10 and an exterior house facade 11.

[0014] Fig. 1 and Fig. Figure 2 also shows that a control device 8 records the temperature and / or humidity values ​​and / or the gap dimension recorded by the sensor 1, and generates an alarm signal when a critical limit value is exceeded or fallen below, thus indicating pending repair work on or near the gap.

[0015] The Fig. 1 and Fig. Figure 2 also shows that the housing is designed in the manner of a flat plate and that the sensor 1 comprises a piezoelectric sensor 2, which is installed in the housing 20 in such a way that external pressure on the outer wall of the housing is at least partially transmitted to an inner wall of the housing 20, and that this pressure at least partially squeezes the piezoelectric crystal 2, which generates a current to operate the control device 8 and / or, in addition to an energy source, such as a battery, an additional signal triggering the current flow is modulated onto the actual operating signal by the squeezing, so that the control device 8 generates an error signal due to this deviation.

[0016] Furthermore, the Fig. 1 and Fig. 2 shows that the piezoelectric crystal 2 also touches the inner wall of the housing 20, at least indirectly.
