Said temperature monitoring device (100) comprises a thermal sensor (110) which faces towards the individual (500). The thermal sensor (110) measures the temperature values in the view area (FOV) and turns them into temperature measurements in matrix form. Such sensors are known in the art. These sensors sense the infrared radiation radiated due to the temperatures of objects and generate value/voltage accordingly.

[0023] The temperature monitoring device (100) also comprises a medium temperature sensor (120). The medium temperature sensor (120) generates a medium temperature value according to the temperature in the medium.

[0024] The temperature monitoring device (100) also comprises a humidity sensor (130). The humidity sensor (130) generates humidity measurements by measuring the humidity in the medium.

[0025] The temperature monitoring device (100) also comprises a distance sensor (140). Said distance sensor (140) generates distance measurements according to the distance of the individual (500) with respect to the distance sensor (140).

[0026] The temperature monitoring device (100) comprises a processor unit (150). Said processor unit (150) is connected to the distance sensor (140), the medium temperature sensor (120), the thermal sensor (110) and the humidity sensor (130). The processor unit (150) takes the measurement values from the sensors they are connected to. The processor unit (150) can be a microprocessor provided on a board. The processor unit (150) can have a processor and temporary and permanent memories for providing realization of predetermined processes by the processor. The processor unit (150) can be a processor unit (150) like Raspberry Pi used commercially.

[0027] The temperature monitoring device (100) also comprises a communication unit (160) associated with the processor unit (150) in a manner providing data exchange. Said communication unit (160) provides connection of the temperature measurement device to a communication network (300). The communication unit (160) can be connected to a communication network (300) by means of a modem, etc. (not illustrated in the figures) in a wired or wireless manner. Said communication network (300) is internet.

[0028] The temperature monitoring system also comprises a server (200) connected to the communication network (300). The temperature monitoring system moreover comprises mobile devices (400) configured to communicate with the server (200). Said mobile devices (400) can be a mobile phone, computer, tablet computer, etc. The mobile devices (400) can comprise an application for processing and displaying of the data coming from the server (200).

[0029] The temperature monitoring system, whose details can be given as above, functions as follows: The temperature monitoring device (100) is placed in a manner facing towards the location (for instance, bed) where the individual (500) like baby, patient, etc. exists. The thermal sensor (110) sends the temperature measurements in matrix form to the processor unit (150). The medium temperature sensor (120) sends the medium temperature measurements to the processor unit (150). The humidity sensor (130) sends the humidity measurements to the processor unit (150). The distance sensor (140) sends the distance measurements to the processor unit (150). The processor unit (150) provides sending these measurements to the processor by means of the communication unit (160). The server (200) selects one of temperature values in matrix form. The highest temperature value is selected by assuming that the highest temperature in the medium will be the body temperature of the individual (500). The server (200) records the temperature value, humidity measurement, distance measurement and medium temperature measurement values to a first database (210). It arranges the selected temperature value according to the humidity measurement values, the distance measurement values and the medium temperature measurement values, in other words, it calibrates the selected temperature value. As a result of this calibration, an individual (500) obtains the body temperature value. The individual (500) records the body temperature to the database together with the related measurements. Thus, all medium measurements and the individual (500) body temperature measurements are recorded. The server (200) also uses the pre-recorded measurement values during the calibration process. In other words, the calibration is continuously improved by realizing machine learning.

[0030] The server sends a warning message to the mobile devices (400) in case the measurement of body temperature of the individual (500) exceeds a predetermined first threshold value and/or in case the measurement of body temperature of the individual (500) is lower than a second threshold value. The server (200) can moreover send the instantaneous individual (500) body temperature or other measurements to the mobile devices (400) in order to be displayed. The first and the second threshold values are selected according to normal body temperature values of the individual (500).

[0031] The server moreover sends message to the mobile devices (400) indicating whether there is an excessively hot object in case the body temperature of the individual (500) exceeds a predetermined third threshold value. The server (200) sends a message, indicating that there is an excessively cold object in the medium, to the mobile device (400) in case the body temperature of the individual (500) is lower than a predetermined fourth threshold value. The first threshold values and the second threshold values are selected at values which may affect the body temperature of the individual (500) in an unfavorable manner much below and much above the normal body temperature of the individual (500).

The light sensor (111) can be a thermal camera, camera, face recognition system, skin recognition system, etc. The processor unit (150) transfers the signals, received from the light sensor (111), to the server (200). The server (200) determines that the sensor is directed to a person in case the received signals meet the predetermined criteria. In case the sensor is a thermal camera, the server (200) receives the thermal image signal and can determine that the thermal image signal is directed to a human in case the thermal image is compliant to the predetermined criteria. In case the sensor is a camera, face recognition system, skin recognition system in a similar manner, it is detected whether the signal is compliant to predetermined criteria or not and it is determined whether the sensor is directed to a human or not. In case it is determined that the sensor is not directed to a human, an error signal is generated.
