- Working voltage: DC 5~36V
- RS232/RS485 to WiFi
- TCP/UDP in WiFi
Electrostatic Protection ESD
- Transparent transmission mode
In this mode, all data that needs to send and receive is not parsed between the serial port and the wifi interface. It minimizes the complexity of user usage.
- AT Command mode
In this mode, the user can query and set the UART and network parameters via AT command.
- HTTP Client mode
Serial data will be submitted to the web server via Http (GET / POST).
- Heartbeat package mechanism
The network heartbeat packet notifies the server that it is in an active state，and it maintains the normal connection with the server by continuously sending the heartbeat packet.
Serial port heartbeat packet notifies the serial device that it is in an active state, and takes the initiative to crawl the sensor data which can not the initiative to push.
- Register package mechanism
Server as a TCP Client and UDP Client, when the the link is established, it sends a predetermined registration package as logo automatically.
Registration package data can be MAC address,or custom registration data.
- AP mode
Without any configuration of mobile devices such as computers or mobile phones, it accesses to the WIFI module for data transmission quickly, the devices are up to 3.
- STA mode
AP+ To achieve long-range or LAN equipment communications via access to router.
- AP + STA mode
It can realize the local equipment LAN communication, and it supports remote device WAN communication, the STA devices are up to 3.
1. Electricity field
- To realize the control center data real-time transmission.
- Low support for 485 communication, to improve anti-jamming and isolation.
- High cost-effective, large-scale application can reduce the overall project costs.
2. Agricultural field
- Monitoring the situation in the greenhouse,such as utilization rate about water resources, fertilizers and so on.
- To obtain farmland information and monitor sudden natural disasters, then to carry out standardized control measures.
- Fully automated operation without human intervention, saving manpower and achieving the precise control of agriculture.
3. Wireless meter reading
- Supports SSL, HTTPS function, to make data transsfer more secturity.
- Remote monitoring meter reading data, saving manpower and resources, and to facilitate the sudden response measures.
- To collect data quickly in the monitoring and management platform, and to facilitate the city electricity management.
