Wireless Multifunction Smart Lora Power Meter for Electric Energy Measurement with Modbus Built-in Relay

Product Description

What is LoRa Wan Communication ?

·LoRaWAN is a low-power wide-area network protocol based on LoRa (Long Range) physical layer modulation technology.

It is designed for IoT devices that require long-distance communication, ultra-low power consumption, and massive connections.

·The core features of lorawan communication include:

    Ultra-long communication distance:In urban environments, it can reach several kilometers, and in suburban or open areas, it can reach more than ten kilometers or even farther.

    Ultra-low power consumption:The terminal device only wakes up briefly when it needs to send data or receive instructions, which allows the electric meter with built-in battery to work for several years or even more than ten years without replacing the battery.

    Large network capacity: A LoRaWAN gateway can connect to thousands of terminal devices (such as electricity meters) at the same time, and the network has good scalability.

    Strong penetration ability: The Sub-GHz frequency band (such as 470MHz, 868MHz, 915MHz, etc.) used by LoRa has strong signal penetration and can effectively cover basements, deep inside buildings and other places where signals are difficult to reach.

    Low cost: Compared with cellular IoT (such as NB-IoT, LTE-M), LoRaWAN's module cost and network deployment/operation cost are generally lower.

    Secure and reliable: Supports end-to-end AES-128 encryption to ensure the security and privacy of data transmission.
