Features

●  Data Collection: Periodically collect data and operational status from instruments/sensors/industrial equipment.

●  Remote Communication: Communicate with the monitoring center via 4G/5G/NB-IoT.

●  Storage Function: Cyclically store monitoring data locally. In the event of a power outage or network disruption, it automatically resumes and resends the data upon restoration, ensuring data integrity.

●  Convenient Maintenance: Enables parameter setting, program upgrades, product debugging, and more via serial port, Bluetooth, or remote network access.

●  Automatic Alarm: Automatically sends an alarm to the monitoring center when data exceeds limits, battery power is too low, etc.

●  External Power Supply: Can provide 5V and 12V DC power.
