The smart water meter of the Internet of Things is composed of dry water meter base meter, electric ball valve, magnetic resistance sensor, MCU, lithium sub-battery pack, LoRaWAN wireless communication module, control circuit and other components. It adopts the electromechanical separation structure design. It has the advantages of long communication distance, large capacity, fast and convenient installation, and long service life.
1. Split structure: the electronic units are relatively independent of the base table.
2. Accurate measurement: using non-contact electronic detection logic and measurement accuracy of 10 liters to ensure the mechanical and electrical consistency.
3. It has the function of touch button wake-up and long press on the button to immediately go online remote data transmission.
4. It has an infrared communication interface, which can read and set relevant parameters.
5. It has various alarm functions: abnormal state, measurement fault, abnormal battery voltage, abnormal valve, etc.
6. LoRaWAN timing uploading function: automatically upload data at set time points (once a day by default), and also receive and execute valid instructions from the platform.
7. Micro-power consumption design: Adopt 3.6V lithium sub-battery pack (ER26500 + HPC1520), with dormant current <10uA.
8. Clock calibration function: Automatic calibration function and remote calibration function of platform after the water meter is connected to the network.

Under the normal state, the water meter will be automatically put online once a day (settable). Through wireless communication, the water meter data will be uploaded to the system platform, and the relevant instructions of the system platform (parameter setting and valve control, etc.) will be received and executed at the same time.
There are touch buttons on the water meter housing. In the dormant state of the water meter, touch the button area with your finger, the red status light on the water meter will flash a little (infrared interface area), the water meter is artificially awakened and in the infrared communication state. If you continue to touch the button (3 seconds), the red indicator of the water meter will flash two times in a row, at this time the water meter will immediately go online (connect to the platform), upload the current data to the system platform and receive the instructions of the platform. The water meter in the process of uploading data, the red indicator will also flash many times in a row. After the meter data is uploaded, it will immediately enter the sleep state (low-power mode).

l. Water meters should be checked frequently to prevent water meter leakage accidents.
lI. In winter, it is necessary to prevent the water meter from freezing and bursting. Installing insulation measures to the water meter when necessary.
lII. When the home is not occupied for a long time, should close the valve in front of the table to prevent water leakage accidents.
lV. Water meter is a measuring product and shall not be destroyed. Destroying water meter is an illegal action.
LoRaWAN Smart Water Meter: The Future of Water Management
Our LoRaWAN Smart Water Meter represents a leap forward in water management technology. This state-of-the-art device combines the groundbreaking LoRaWAN protocol with advanced metering technology to deliver real-time, secure, and accurate water usage data.
Long-Range Communication: Our device uses LoRaWAN, a low-power, wide-area network protocol, designed to communicate over several kilometers in rural areas and several hundred meters in urban settings. This ensures reliable data transmission, no matter where your meter is located.
