Internet-of-things patch-type sensor device and sensing information monitoring system and sensing information monitoring method using same

An Internet-of-Things (IoT) patch-type sensor device comprising:

• a lower plate unit configured to detachably couple with an object to be measured;
• a control plate unit configured to stack and fasten on the lower plate unit;
• and
• an upper plate unit configured to stack and fasten on the control plate unit,
• wherein the lower plate unit comprises a contact conduction portion configured to transmit measurement information of the object to be measured through contact with the object to be measured, and
• the control plate unit comprises a power terminal portion configured to apply power, a wireless communication portion configured to perform wireless transmission of the measurement information and mutual communication with an outside, a sensing module configured to generate sensing information by sensing the measurement information transmitted from the contact conduction portion, an identification tag configured to embed with an identification code of the sensing module, a display module configured to display an operation status of the sensing module and a communication status of the wireless communication portion, and a controller configured to control an operation of the wireless communication portion, the sensing module, and the display module, and
• the upper plate unit comprises a power connector configured to connect to the power terminal portion and a display window configured to display the display module.
