Lora Gateway (GPRS/3G/4G/Ethernet+Lora)
S281 upgrade, please refer to S281 latest version https://gateway-iot.com/lora-gateway-p00308p1.html
The 4G Lora Gateway S281 is the latest Lora technology for industrial internet of things solutions. It supports upto 99 wireless temperature humidity modules, the wireless temperature humidity sensor powered up by normal AAA battery, and 99 wireless serial port modules with a monitoring radius of upto 2500m.
4G Lora Gateway S281 is widely used in agricultural greenhouse temperature and humidity collection and monitoring, chemical plant temperature and humidity collection and monitoring, electroplating plant temperature and humidity collection and monitoring, hospital sites and fruit and vegetable storage warehouses and other places temperature and humidity collection and monitoring.
4G Lora Gateway S281 Supports SMS,GPRS,3G, 4G Lte Cellular Networks. Compatible Modbus TCP and MQTT IoT Protocols and can intergrate to the KPIIOT IoT Cloud Platform and OPC, SCADA and MES systems to build an industiral IoT Solution.
Wide working voltage design, support 9 ~ 36VDC power supply, and anti-reverse protection design;
Modular structure design, GSM / 3G / 4G network upgrade only needs to replace the module to realize the network upgrade;
Support remote SMS to restart the device and configure device parameters;
Using local configuration software, remote SMS, APP to set parameters, easy to operate and easy to use;
Supports 10 user numbers for receiving device daily reports, dropped calls, serial port data overrun, and specific SMS alarm messages triggered abnormally;
Built-in powerful timer function, support timing automatic reporting, timing SMS daily report, timing online, timing restart and other functions;
Modbus TCP protocol and Modbus RTU protocol are compatible with transparent transmission;
Ethernet comes with a transformer isolator, 2KV electromagnetic isolation, and shell isolation protection;
Adopt time division multiplexing, multi-channel mounting, less interference, more mounting nodes, can support up to 99 temperature and humidity collection points
It can monitor the terminal battery level in real time to ensure that the device data does not drop.
