CS01-NB/NS
NB-IoT 4 Channels Current Sensor Converter
The Dragino CS01-NB/NS is a NB-IoT 4 Channels Current Sensor Converter. It can convert the reading from current sensors and then upload to IoT server via NB-IoT network. CS01-NB/NS can be used to monitor the machine running status and analyze power consumption trends. The CS01-NB/NS supports maximum 4 current sensors. The current sensors are detachable and can be replaced with different scales.

Application guide
Choose the airflow range by deployment scenario

Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.

HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.

Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
