16 AIS is a video photo recognition sensor, the sensor can be used in electricity meters, gas meters, water meters, pressure gauges and other types of meters. Accurately identify the number of the current dial or upload the picture of the current dial for comparison, which can replace people to go to the door to read the meter, and is more accurate and energy-saving than the meter. The first thing to do is to fix the AIS sensor, the end direction needs to be aligned with the object that needs to be identified, you can check whether the object all appears in the lens range through the upper computer, and then calibrate, Chapter 2 will explain the calibration method of different tables.

30
31
32 This water meter is designed in accordance with the Chinese standard for drinking cold water meters and hot water meters, GB/T 778.1-2007. It features five dial numbers for measurement accuracy.

35 === 2.1.2 Fix Sensor to a Water Meter ===
36
37
38 The assembly necessitates the use of two screws, two spacers, and this specific device.
39
40 Additionally, there are AIS Sensors available along with AUC USB TTL adapters for AIS Sensors.
41
42 The fixture below is just a demo, user might adjust it with their water meter. Here is the STEP file for the fixture as below: [[Water Meter Fixture Demo>>https://www.dropbox.com/scl/fo/p1ykgysrv8p454swsh4zj/AHCYr5pcOM0WNad4fT1sf_I?rlkey=7x964q1tuvh0ezbhgxb9b2zqg&st=wxxq87t3&dl=0]].

45
46 The procedure is as follows:
47
48 ~1. Secure back of the AIS sensor  onto the small board and adjust its position according to your requirements. You may use two additional screws for fixation or utilize 3M double-sided adhesive for attachment.
49

51
52
53 2. Proceed by fastening the device using the previously prepared screws and gaskets.
54
55 [[image:image-20240428165354-5.gif]]
56
57
58 3. Finally, nestle the device onto your water meter, ensuring that it can be adjusted to meet your specific needs while guaranteeing that the camera is directed towards the digital wheel face.

448 Once all the data has been uploaded to the TTN platform, the subsequent step involves concatenating each packet in sequential order and saving it into a new TXT file. It is important to note that the first 8 bytes of each packet should be removed before concatenation.
449
450 When you combine all the packets, you need to convert the data inside to binary. Here the conversion is demonstrated using the [[WinHex>>http://www.x-ways.net/winhex/index-m.html]] software.
