Description

As a debugger, it can send SDI12 commands to sensors that conform to the SDI-12 protocol through the USB-TTL serial port, and return information through the serial port, which can capture the bidirectional data on the SDI12 protocol bus.

As a data collector, you can set the collection time interval to automatically collect data. By default, the collector sends two commands, ?M! and ?D0! (? is the sensor address), and stores the data returned by the sensor in a file. 10 sensors are collected in parallel at the same time.

Plug in the USB cable in U disk mode, the TF card can be recognized as a U disk, and data can be quickly copied through a computer or smartphone.

SDI-12 protocol capturer debugger multifunctional data logger.

Features are as follows:

1. Both SDI-12 data collector and SDI-12 debugger;

2. Support user-defined acquisition commands (2);

3. TF card and FAT32 file system are used to store the SDI-12 sensor data collected by the user, the data is stored in CSV format or text file format, and the user can set the file number, and the maximum support 32G TF card;

4. Support user-defined storage file size, if the size is exceeded, a new storage file will be created automatically;

5. The system has its own clock and backup battery, which can record the time of data collection in real time;

6. The system can be powered by DC 3.6V-12V battery, and the standby current is about 1.7mA when the TF card is inserted;

7. When collecting data, the battery supply voltage can be collected at the same time and stored in the TF card as a parameter;

8. The user can set parameters such as storage time, whether the light flashes, baud rate, etc. The set parameters will not be lost when power off;

9. SDI-12 signal drive capability can be set, which can improve the transmission distance of SDI-12 signal and multi-sensor drive capability;

10. Real-time monitoring of TF card, LED light prompts when TF card fails;

11. The user can order to set the system time, obtain the system time and related parameters, etc.;

12. Support multiple SDI-12 sensors in parallel to achieve multi-sensor acquisition and storage.
