Products Description
Self developing and manufacturing nb iot module for wireless smart meters
The advantage of the NB-IoT tramsmission module
Remotereading
Periodically and actively report the reading and status of the meter, and adopt the discrete reporting mechanism to prevent server congestion resulted from a large number of terminals reporting at the same time;
Remote valve control （option)
Preset commands to close or open the valve remotely, with manual wake-up mode, trigger the meter terminal to actively communicate with the server to receive valve control instructions, wake up by touch;
Prepaid(option)
Support system, APP prepaid recharge, can support NB-IoT remote recharge and credit card recharge at the same time;Close the valve automatically when the fee is overdue.
Warning system
Alarming in case of low battery voltage, abnormal measurement, magnetic attack, Pre-paid quantity and prepaid amount reaches the limit ,etc. Smart water meters can set different emergency water consumption for different users;
Ladder price
The water, gas , electricity price can be set as tiered price according to user category and usage;
Ultra-long life combined battery
Standard ER26500 battery + SPC1520 battery capacitor combination power supply guarantees more than 6 years of use without
replacement;
Data storage function
Can store data of no less than 31 days. When the storage data is full in the storage medium, the newly collected data
automatically overwrites the earliest data, and the data within the storage period can be supplemented;
Internal / external antenna
Support internal / external antenna, stable and reliable signal, full coverage and no blind area;
Support multiple sampling modes
Support sampling methods such as photoelectric, Hall, reed switch, magnetic switch, ultrasonic etc, reading accuracy can reach100%;
Hall or reed switch sensor failure detection
When a sampling reed switch fails, the meter will automatically upload a reed switch failure alarm.
Flexible upload frequency setting
The data upload cycle can be set to meet the management needs of different users. The uploaded data can include traffic that does not exceed one hour on the day (no less than 24 groups of data per day), and daily cumulative traffic, which is convenient for
traffic monitoring;
Data resend and reissue mechanism
When one uploading fails, it will start multiple repeated uploading; If the re-uploading still fails, it will start the reissue
mechanism. When it comes to the next uploading cycle,the data that failed to reissue will be resubmitted automatically.
The system adopts BS architecture
Don’t need any APP download, just need browser login.Support both PC and mobile phone.

The function of the LoRaWAN module
The NB-IoT module transmits and receives data wirelessly through NB-IoT module,and has characteristics of ultra-small size, ultra-low power
consumption, strong performance and ultra-long transmission distance. The NB-IoT network has been widely covered, and the module's
RF chip has the characteristics of high anti-interference, high reliability, and low power consumption.This module solves the
problems that traditional design solutions cannot simultaneously take into account long-distance, anti-interference, low power
consumption, wide signal coverage and ease of installation, and has become the best choice for reliable long-distance transmission
applications.
