LoRa terminal
The LoRa terminal developed and produced by Chengdu Zongheng Intelligent Control Technology uses low-frequency half-duplex and supports point-to-point and point-to-multi networking. There are currently 2 product models, namely ZHC0561 and ZHC0661. Among them, ZHC0561 provides 1RS485/4DI/2DO interface. ZHC0661 provides RS485/4AI/2AO interface. Supports local logical settings and inter-device logical settings, and supports AES communication encryption. Using the serial port for sending and receiving lowers the threshold for wireless applications and enables data transmission from the serial port to LoRa. LoRa has the advantages of concentrated power density and strong anti-interference ability. The communication distance of this product can reach 8000m. Suitable for applications in smart meter reading, smart oil fields, agricultural monitoring, industrial manufacturing, smart buildings and other fields.

LoRa networking
Self-organizing network, flexible usage
LoRa 4G gateway
The combination of LoRa RTU and 4G RTU can transmit the LoRa RTU transmission data to the server through the 4G network. The server can also issue commands to the LoRa RTU through the 4G network.
Application of LoRa terminal
LoRa DTU adopts humanized design. Users do not need to understand the complicated data transmission process. They can send and receive wireless data through LoRa DTU software and hardware. LoRa has outstanding low power consumption and long-distance transmission capabilities, and is suitable for use in some long-distance and small-bandwidth situations. This product can be widely used in long-distance meter reading of water, electricity and gas, power monitoring, hydrology and water resources monitoring, flash flood and geological disaster monitoring and early warning, environmental pollution monitoring, climate data collection, forest fire monitoring, industrial long-distance data collection/transmission, etc. category.
