Abstract
The field of metrology is mainly legal metrology; seals are closely related to the guarantee or validity of a measuring instrument. Seals are designed so that it is not easy for other parties to open the seal. Seal damage must be identified as soon as possible. The application of the Internet of Things (IoT) is needed in the process of sending data in real-time. IoT technology can be applied to electronic seals to know and record the condition of the measuring device. Broken seals caused by irresponsible parties can cause losses to consumers and owners of measuring instruments. Electronic seals are expected to be able to detect seal damage caused by abuse of authority or fraud. The broken seal will send data to the server as well as SMS (Short Message Service) to the related party. Electronic seals can send damage data via SMS within 20 seconds with a success rate of 92% and sending data through the ThingSpeak web server within 40 seconds with a success rate of 82%.

Summary
Based on Law No 2 of 1981 concerning Legal Metrology, Metrology is the science of general measuring. It is not uncommon for officers to commit fraud by making a fake sign so that the UTTP device used looks like it has been through an illumination procedure when inspected by a person who is being interviewed. To reduce these acts of cheating, the parties use the seal or stamp function as a guarantee of the validity of the UTTP tool that has been done the verification. In the field of metrology, especially legal metrology, seals are closely related to the guarantee or validity of a measuring instrument. Development of electronic seals is expected to be able to overcome the problems that occur in the field so that government programs in an orderly manner can be implemented
