Factory wholesale wireless water meter data logger - LoRaWAN Dual-mode Meter Reading Module – HAC Detail:

System Components

HAC-MLLW (LoRaWAN dual-mode meter reading module), HAC-GW-LW (LoRaWAN gateway), HAC-RHU-LW (LoRaWAN handhels) and data management platform.

System Features

1. Ultra long distance communication

LoRa modulation mode, long communication distance.

Visual communication distance between Gateway and Meter: 1km-5km in urban environment, 5-15km in rural environment.

The communication rate between the gateway and the meter is adaptive, realizing the longest distance communication at a low rate.

The handhelds has a long supplementary reading distance, and batch meter reading can be carried out by broadcasting within a range of 4km.

2. Ultra-low power consumption, long service life

The average power consumption of the dual-mode meter-end module is less than or equal to 20µA, without adding additional hardware circuits and costs.

The meter module reports data every 24 hours, powered with an ER18505 battery or equal capacity can used for 10 years.

3. Anti-interference, high reliability

Multi-frequency and multi-rate automatic switching to avoid co-channel interference and improve transmission reliability.

Adopt the patented technology of TDMA communication to automatically synchronize the communication time unit to avoid data collision.

OTAA air activation is adopted, and the encryption key is automatically generated when entering the network.

The data is encrypted with multiple keys for high security.

4. Large management capacity

One LoRaWAN gateway can support up to 10,000 meters.

It can save 10-year annual frozen and monthly frozen data for the last 128 months. The cloud platform can query historical data.

Adopt the adaptive algorithm of transmission rate and transmission distance to effectively improve the system capacity.

Easy system expansion: compatible with water meters, gas meters and heat meters, easy to increase or decrease, gateway resources can be shared.

Compliant with the LORAWAN1.0.2 protocol, the expansion is simple, and the capacity can be increased by adding a gateway.

5. Easy to install and use, high success rate of meter reading

The module adopts OTAA network access method, which is easy to operate and easy to maintain.

Gateway with multi-channel design can simultaneously receive data of multi-frequency and multi-rate.

The meter-end module and the gateway are connected in a star network, which is a simple structure, convenient connection and relatively easy management and maintenance.
