LoRaWAN infrared wireless meter reading module

Product Model:HAC-MLW3

  HAC-MLW3 is a new generation of wireless communication products for integrated metering applications. Including data acquisition and wireless transmission functions, it has the characteristics of ultra-low power consumption, low delay, anti-interference, reliable performance, simple OTAA network access operation, high security of data multiple encryption, convenient installation, small size, and long transmission distance.

The data reporting method of HAC-MLW3 has two options: touch button reporting or magnet trigger reporting, and supports infrared parameter setting and upgrade.

Features

1) Comply with the international general standard LoRaWAN protocol formulated by the LoRa Alliance.

● Using OTAA to actively access the network, the module automatically joins the network.

2 sets of unique secret keys are generated during network access for communication encryption, with high data security

● Enable ADR function, realize automatic switching of frequency and rate, avoid interference, and improve the quality of single communication.

● It can realize automatic switching of multi-channel and multi-rate, and effectively improve the system capacity.

2) Actively send data once every 24 hours, support infrared upgrade.

3) The communication mode of TDMA time division multiple access automatically synchronizes the communication time unit, which can completely avoid data collision.

4) It integrates functions such as acquisition, metering, valve control, wireless communication, soft clock, low power consumption, power management, and magnetic attack alarm.

● Support single and double pulse measurement (Hall, reed switch, non-magnetic, etc.), direct reading measurement can also be purchased, and the measurement method is fixed before leaving the factory.

● Power management function, detect the transmission status or control valve voltage and report it.

● Magnetic attack detection function, which generates alarm signs when detecting malicious magnetic attacks.

● Support power-off storage function. After the module is powered off, it does not need to re-initialize the metering value.

● Support valve control, the valve can be controlled by sending commands from the cloud platform.

● Support frozen data reading, the cloud platform can send commands to read monthly frozen data and annual frozen data.

● Support dredging valve function, which is configured by the host computer.

● Support power-off closing valve.

● Support near-end infrared parameter setting.

5) Use the magnetic trigger meter terminal to manually report data or press the button to trigger the report data, and the meter terminal will automatically report data regularly.

6) Standard spring antenna, flexible circuit board antenna or other metal antenna can also be customized according to user products.

7) Optional welding Farad capacitors (or welding by users themselves).

8) Optional 3.6Ah capacity lithium ER18505 battery, customized waterproof connector.
