Tính năng của sản phẩm

Black Technology of future IoT-LoRa

Long communication distance, low power consumption, anti-interference, high sensitivity and low cost.

Good choice of communication project with long distance.

Support LoRaWAN protocol.

Basic function

Bidirectional transparent transmission between TTL interface and LoRa.

Frequency band

SX127X solution

Ultra-low power demand design

Powerful anti-interference capacity

Ultra-low power consumption

Greatly extend battery life, be adaptive to connection rate and sleep current can be only 2μA.

Reduce power consumption

Long communication distance

Long transmission distance and powerful penetrating power.

Data transmission is more stable than traditional model.

Be suited to long-distance data collection.

Anti-interference  High sensitivity

Unique signal frequency spectrum amplification

Receiving sensitivity can reach -130dBm

Watchdog

Software watchdog design which can realize 24 hours stable operation

Security

Dual 128AES encryption mechanism to provide secure communication mechanism

Three elements of security: confidentiality, integrality and availability. 

Work mode

Class A devices only enable receiving window when they are transmitting to maximize power consumption reduction

Power consumption comparison diagram of three work modes

Access way

Access way has OTAA and ABP two ways:

ABP way-Save accessing network information on device in advance and device can access network directly after powering on.

OTAA way-Device won’t access network after powering and user needs to operate device to access network

Applications

Smart metering

Can realize long-distance data collection to improve work efficiency

Low power consumption and adjustable  transmission rate, which can reduce battery change frequency

Arrange nodes reasonably which can help management and all-sided detection 

Smart oil field

Real-time detection to devices which can help management

Long-distance and wireless transmission, and free from the tariff cost

Arrange nodes reasonably which can help management and all-sided detection 

Smart agriculture

Data transmission with low power consumption which can reduce operation cost

Timely and valid data transmission, and it can improve agricultural yield and avoid waste of resources

Long-distance and stable transparent transmission, and high-precision working process to help to increase revenue
