1. Introduction
누수감지센서(제품)은 상수도관에 부착되어 수도관의 누수 시 발생하는 진동을 측정하기 위한 무
선 측정 장치이다.
시에라 3G 모뎀이 내장되어 있으며 측정된 주요 데이터는 무선으로 서버에 전송이 되며, 이 데이
터는 모바일 앱 또는 PC 프로그램을 통해 확인 가능하다.
일차 리튬 배터리가 내장되어 있으며 저전력으로 동작하기 위해 평소에는 저전력 상태의 대기 모
드로 있으며 정해진 시간에만 깨어나 동작하도록 되어 있다.
The leak detection sensor (product) is a radio measurement device attached to the water supply
pipe to measure the vibration occurring when the water pipe leaks.
The Sierra 3G modem is built in, and the main measured data is transmitted wirelessly to the
server, which can be viewed via a mobile app or PC program.
It has a built-in primary lithium battery and is normally in standby mode with low power to
operate at low power and it wakes up only at a fixed time.

2.1. Product
모델명: ULD-3G001
주요 기능
- 케이스 하단에 있는 누수 감지 센서의 정보를 3G 모뎀을 통해 서버에 데이터를 전달하
는 IOT 제품
- 하루에 약 4회 통신을 하며 그 외 시간은 대기 모드로 있으며, 이는 저전력 상태를 의미
기타:
- FCC 인증을 위해 자석으로 리드스위치에 터치하여 파워 온을 한 경우 3시간 연속 동작
하도록 펌웨어 변경된 시료 전달 예정 (UART 포트로 동작 확인 가능)
- 외부 포트는 UART 통신용이며 일정 시간 주기로 데이터 출력 (115200bps)
- 통신 모뎀은 개통되지 않은 상태로 시료 전달 예정
전원 켜기: 케이스 하단에 둥근 스티커에 자석으로 짧게 터치하면 전원 켜짐
전원이 켜지면 외부 콘넥터를 통해 데이터가 출력 됨. (일정 주기)
Model name: ULD-3G001
Main function
- IOT products that transmit data to the server through the 3G modem for leak detection
sensor information at the bottom of the case
- It communicates about 4 times a day and other time is in standby mode, which means low
power state
Other
- When the power is turned on by touching the reed switch with the magnet for FCC
certification, the changed sample will be delivered for 3 hours continuous operation (UART port
can be confirmed)
- External port is for UART communication and data output (115200bps)
- The communication modem will not be opened and the sample will be delivered.
Power on: Touch the circle sticker at the bottom of the case with a magnet to power on
Data is output through external connector when power is turned on. (Fixed cycle)

2.2. Main Board
메인보드에는 외부 인터페이스용 콘넥터와 배터리가 연결이 된다. 보드의 하단에는 누수 감지용
진동 센서의 콘넥터를 연결한다.
메인보드의 상단에 모뎀 모듈을 체결한다. 모뎀 모듈의 하단에는 유심 콘넥터가 있다.
The external interface connector and battery are connected to the main board. Connect the
connector of the vibration sensor for leakage detection to the bottom of the board.
Tighten the modem module to the top of the main board. There is a sim connector at the bottom
of the modem module.

 UART
A universal asynchronous receiver-transmitter (UART) is a computer hardware device for
asynchronous serial communication in which the data format and transmission speeds are
configurable. The electric signaling levels and methods are handled by a driver circuit external to
the UART.

Note: This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
§15.21 Information to user.
The users manual or instruction manual for an intentional or unintentional radiator shall
caution the user that changes or modifications not expressly approved by the party
