SC-GP-IL02 is a 4G/GPRS-based wireless dual-axis tilt sensor transmitter launched by Shanghai Data Acquisition Internet of Things Technology Co., Ltd. The measuring range is ±60 degrees. This product is widely used in angle measurement, high-altitude mechanical operation platform monitoring, dams, bridges, inclination and attitude recording, bending control and other fields.
The sensor terminal supports the use of GPRS/4G/NB-IOT/LoRa/WiFi communication methods (the external power supply uses GPRS communication by default, and the battery power supply uses NB-IOT/LoRa communication by default), which can overcome the wireless communication obstruction caused by the special environment on site. Greatly simplify on-site deployment time and reduce construction costs.
Model feature description
SC-LP-IL02 NB-IOT / loRa communication, long-life lithium battery power supply, suitable for occasions with low acquisition frequency and difficult external power supply.
SC-GP-IL02 GPRS communication, 220V AC/12V DC power supply, suitable for occasions with high acquisition frequency or convenient external power supply. Because the device is online for a long time by default, it can support remote configuration parameter debugging, and only need to install and connect on site.

5 data reporting communication protocol
5.1 protocol analysis description
UDP/TCP/MQTT/HTTP and other push methods, To receive data, users need to provide the public IP (or domain name) address and port number of the cloud server.
Example of JSON format data message:
{"X":-16.7,"Y":55.8,"ID":"860344048491162"}
Message analysis:
{
"X": -16.7, //X-axis inclination value
"Y" : 55.8, //Y axis inclination value
"ID": "
5.2 Protocol customization
If you need to customize other communication protocols, you can contact sales personnel for communication. The order of this product is more than 1,000 yuan, and the communication protocol is customized for free.
6 Platform docking
6.1 Default platform The
product is connected to the industrial IoT platform designated by our company by default. The platform interface is as follows:
Computer browser interface
Mobile phone WeChat access interface
6.2 User-designated platform
Take the Alibaba Cloud platform docking as an example. After the user creates a product and adds a device on the Alibaba Cloud IoT platform, the user needs to provide a triple: {ProductKey, DeviceName, DeviceSecret} and the desired release MQTT theme.
For example, the values of the triples are:
ProductKey = b0FMK1Ga5cp
DeviceName = 862991419835241
DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q

8 Precautions for tilt monitoring of large structural parts
(1) When installing the sensor, incorrect installation will cause the measurement error to increase. It is necessary to ensure the correct installation of the two sides and two wires.
The two sides mean that the mounting surface of the sensor is completely close to the mounting surface of the measured object (the mounting surface of the measured object should be as level as possible), and there should be no included angle (angle a in the figure below). The correct installation method is shown in figure B.
The two lines mean that the sensor axis is parallel to the axis of the measured surface, and the two axes cannot have an angle (such as angle b in Figure C). The correct installation method is shown in Figure D.
(2) This product has a built-in IoT SIM card by default. The first year is free, and the data fee is about 20 yuan per year from the next year. If you need to use your own SIM card, please inform in advance.
(3) Instructions on the collection of traffic charges: During the on-site operation of the equipment, parameters such as the IP port, reporting period, and communication protocol can still be changed remotely according to user requirements. br/>9 Contact Information
