Real-World Use Case
A farm uses the CPL03-NS (solar version) to monitor the status of irrigation control cabinets across the property. Whenever a cabinet door is opened, the sensor sends a signal over NB-IoT to the farm’s monitoring platform, ensuring any maintenance or unauthorized access is recorded instantly.
