[0001] The present invention relates to a physical quantity measuring device that is interlocked with a terminal, and more particularly to a physical quantity measuring device that measures physical quantities such as temperature, gas, and humidity of a contact object with a measurement sensor, converts measured results into data, Which is capable of improving the accuracy of the correction of the physical quantity by receiving the physical quantity data of the measurement object in real time and easily monitoring the change of the data by transmitting the data to the terminal using the low power Bluetooth .

A physical quantity is a quantitative representation of a state of a measurable material system and is classified into basic quantities such as temperature, time, mass, length, luminosity, current, capacity, and various quantities that can be expressed in appropriate combinations from the base quantities.

Generally, such physical quantities are measured using sensors, for example, in industrial and various fields, using sensors with built-in sensors. In recent years, electronic devices such as a smart phone and a tablet PC have built in sensors for measuring physical quantities.

However, these devices and devices have a single sensor that measures only specific physical quantities. For example, since only the temperature measuring sensor is included in the temperature measuring device, it is impossible to measure a physical quantity other than the temperature.

In addition, since the sensor is built in the device and the device, it is not easy to maintain, and if the sensor malfunctions, the processing cost for replacement and repair is uneconomical.

Moreover, there is no means or method that can be compared with the physical quantity data measured in the past, and it is inconvenient to clearly grasp the physical quantity transition of the measurement object.
