IoT measurement device maintenance
Fines/suspension for failure to maintain IoT measuring devices

IoT measuring devices require attachment number maintenance and are divided into H/W and S/W maintenance. H/W is on-site inspection and replacement management due to equipment failure or aging, and S/W is measured data and program management. Since they are not compatible with IoT measurement device developers, only the requested IoT measurement device company can facilitate maintenance. .

On-site autonomous S/W management with various programs

Once attached, USIoT-1000 enables autonomous S/W management at the workplace.
Through various programs, you can operate IoT measuring devices with minimal maintenance costs through on-site self-inspection or call center support.

Long-term H/W maintenance

From May 2023, only IoT measuring devices that apply the latest communication protocol v3.0 can be attached. Currently, the company registered with the Korea Environment Corporation is headquartered in the Gyeongsang region among 21 IoT development companies nationwide, enabling quick and economical maintenance in the region.

Avoid environmental regulations through warning notifications

When data from IoT measuring devices attached to business facilities is transmitted to the Korea Environment Corporation, the transmitted data becomes the standard for environmental regulations. USIoT-1000 monitoring's warning notification allows preemptive measures to be taken at business facilities before environmental regulation standards are exceeded.
